Here are some evidence, now whether the evidence is conclusive is a different story, that is for you to decide.
Most of this evidence you are probably very familiar with.
As I said earlier, even I could definitively convince the evidence is sufficient to prove to you God existence, it does not change the fact that some would disapprove of him regardless.
General Evidence:
(1) The complexity of creation and the fragility of life. For example the human brain is one of the complex things in the universe, it is able to understand profound concepts such as quantum physics or higher level mechanics, it is able to reason, rationalise, think, stimulate etc. The intricate balance of life, such as the small precision required in certain circumstances (e.g. temperature, gravity), make the Earth an thriving habitat for life, unique in the solar system and possibly in the galaxy. Even the fine tuning of the universe, if it was unstable or slightly off, would have been catastrophic for life. Even the general human regard for life and acknowledgement that we need to take care not just of our species but also for our environment.
The intricateness and particular the order (which science has definitely proven) can't originate from a causeless or random chaotic cause (of which I would include a multiverse), order indeed must be instituted by a cause that is ordered. Thus it implies an ordered creator
(2) The creation of time and space. Since time and space has an origin, unlike the Steady State theory which has been disproven. The universe is finite in existence, despite being incomprehensible in size, it still has a finite size, otherwise the Big Bang would not be a valid theory.
The fact of a beginning to space and time, implies directly something beyond space and time. It also implies a creator, but by itself this evidence does not definitely prove it
(3) Absolutely morality. The idea of what is right and wrong, becomes subjective if God does not exist. In fact the strongest piece of evidence for God's existence is the very fact we have a consciousness and have the ability to distinguish between right and wrong. In fact no matter what race, religion, language or tribal group, many people consent to certain things as being good, at the same time disapprove of other things
If there God exists, that the distinction between right and wrong is not subjective, which means there is actually of some benefit to doing right and wrong. If the distinction between right and wrong is merely subjective, and there is no absolute standard, then a person can easily justify what they do even though others may view as wrong, misguided; as acceptable. If it is subjective, there is no reason to do right other than to advance the evolution of the human race. If that is the case, how come we become complacent and forget those in the past. We claim to remember, but if we actually examine, we don't tend to remember. Also at funerals, how come we only tend to say good things or say a cliché "he/she will be looking down on us, smiling at us". If God does not exist, then you have to ask what is the goal of life? To give your best shot
Conclusion pt 1: Those of some of the arguments, obviously their are little 'ifs' and buts. But this is the groundwork.
Observations/Comments from a non-general perspective:
[1] The God is paganism is very simple and finite - you see him/her in the mirror every day. If God was that simple, I would be incredibly disappointed, because if you analyse your life, it is really disappointing. In fact we only know some of the answers, enough for some to have faith, but not having all answers is more comfortable, then to simply know/have answers to everything.
[2] The writer of the book of Ecclesiastes was a philosopher, who observed how good men and bad men suffered the same fate of death. He also noted the futility of things such as riches and work. Especially because of the fact, that people die, and don't really end up benefiting the very goals and things they worked towards. For example, the people that died serving in wars did not end up benefiting their labours, but rather we who are left behind.
[3] Christians believe that the Bible is the infallible and inerrant word of God, and they also believe that God has given enough clues in creation and in the conscious/moral reason and rationality of creation and the mind of man, to know that God exists. In fact they believe that God has indeed written is laws on our hearts and that our conscious bears witness when we break the standards of God's law (what is good)
[4] The fact that we cringe at the idea of God's existence is something that is also well documented.
(From about here on, you may find disagreeable much...)
Specific Evidence:
(investigating the specific claims)
(1) If we consider for example the account of Jesus' resurrection, there is no just one historical source.
Of the New Testament, there are 20,000 thousand manuscripts, compared to less than 10 for other historical events/figures.
Of particular interest is the fact that there are least 4 separate distinct accounts of the resurrection. They differ on details, which rather than contradicting, actually provides validity. They have odd details, details that wouldn't be characteristic of a forgery or a made-up fairy story.
(e.g. the first person to see Jesus was a women in a time when women's testimony was seen as inferior to that of men in that historical period/context, and that if you were to make a story, you would not put the women as having key roles).
Other details include the presence of body-guards and a large stone that would have required several men to roll away, yet the women didn't bother to get anyone to help them roll away the stone. And the fact that the stone was rolled away, the tomb was empty as well). Some of these accounts also document an attempted cover-up by the Pharisees who were indeed envious of Jesus.
(2) Historical writings from pagan/Roman sources verify the existence of Jesus as many people would acknowledge existed and also verify the claims of the Christians, and the very fact that they are being persecuted back then (as indeed they are today). Recently a source was discovered other than the accounts we call the Gospels, that affirmed a miracle that Jesus performed.
Most people nowadays view Jesus as a good teacher but slightly misguided, some people recognise that he performed miracles, others trust in him.
In fact back then it was a bit easier, because you could ask a person, and they would testify that they had indeed seen the Jesus after his death IRL (in the flesh). Paul even lists specific names and numbers.
Some would then argue, did Jesus die? Well according to the Roman historian Tacitus, he did. And analysing John's account particularly seems scientifically accurate that Jesus had indeed died at the hands of the Roman crucifixion methods.
Other interesting evidence:
The Bible is actually a collection of books written over several centuries apart, different writers. Jews accept what constitutes most of the Old Testament (22 books, of which a lot of the later books are split up by Christians into separate writings)
*predicted can be replaced by prophesied
The book of Daniel for example was written when Babylon was in power, and predicts* that the king of Greece would defeat the Persian empire before it actually happened.
The book of Jeremiah written even earlier when the kingdom of Israel was still in power, predicted that Judah would be defeated by Babylon, and that even Egypt would be defeated by Babylon; and also that the Persian ruler that would release the exiles back to Judah's name is Cyrus.
Jesus even prophesised of the fall and destruction of Jerusalem in 70AD, as well as the pagan desolation of the temple that followed afterwards by Hadrian.
Jesus even prophesised of the persecution of his followers. In fact, the apostles of Jesus; as well as Paul, all died at the hands of the Romans because of their testimony to Jesus. James, the brother of Jesus was beheaded. Stephen was stoned, Peter crucified as well.
The other thing is the countless prophecies which refer to the work of Jesus, notably in the later half of Isaiah which was written 700 BC and also in the Psalms written earlier, even all the way back to Genesis 3 (said to be written by Moses approximately 3000 years before Jesus).
-----------------
To conclude, the evidence is there. The question is whether there is SUFFICIENT evidence, for you to believe that God exists. For some people there isn't. For some people there is, but then there are other philosophical problems or paradoxes to deal with. Still others there is, and they are willing to believe. I can't speak very well for other religions, but I am sure some of them would be able to present a similar case.
We should always given a reason for why we believe what we believe.
