Simplest explanation
an unobserved, omnipotent, omniscient, intelligent force that exists outside of all established and observed rules of reality, designed the universe 14 billion years ago, specifically designing this infinitely vast space so that 14 billion years into it's infinitely long existence, a species that will flit out of existence in an infinestimally small portion of the universes existence (likely a few hundred thousand years) would consume, fuck, and kill each other on the surface of this tiny dot depicted here:

Simple and elegant
Hahahahha
Probably one of the worst arguments against an argument for design, you have literally not touched any of the points made by an argument by design (such as Fine-tuning of initial conditions among the great complexities), and instead tried to argue that the universe is not designed because it looks as though we are insignificant in
size.
Yet as far as we know we are the only rational intelligent animals in the universe.
because the universe is so much more complex than a being that has within it the power to make said complex world. a being that defies all natural laws as we know it.
so occam wow
Rather
Design in the universe implies a designer
Combine this with the concept of an uncreated Creator to prevent an infinite regress of past events, and so we must eventually conclude that this designer is some Omnipotent, Intelligent, Powerful designer.
It is not the job of the design argument (or cosmological) alone to describe a precise formula for an Abrahamic God. (Though at this point if you accept the arguments you are at least a theist)
We muster the concept that God since he designed the universe and us inside, He'd send us a message of some sort. Then we analyse the scriptures to try and find an uncorrupted version that supports God most logically, and common-sensically
We find scriptures themselves (other than Islam) predict Prophet Muhammad
We find scriptures of most religions have been distorted
We reject the concept of God coming down in the form of a man due to the logical impossibility and contradiction
We find that the religion that adheres to the above is Islam.
And so I don't say that you can rigorously prove that Islam is the truth purely through axiomatic reasoning
But rather that the probability that God exists and Islam is true is too great to reject

Essentially this is what it comes down to, do you have faith in the god of atheism named chance (nor do we use the concept of insurmountable odds in our daily lives), or do you believe in Allah (SWTA).
