My common argument is that if we were created, God had to have been created. By their logic, we can't have been a product of nothing have thus, must have been created. Same rules apply to a creator in my book.
going off on what basically the Aztecs and Egyptians said, and what modern science has been pointing to when it comes to the classification of civilizations in the universe, its more logical to say that we were created by a more advanced civilization, one that was playing god and slicing DNA to make all living creatures at least on this planet. hell we humans have been experimenting around with DNA manipulation it isn't too far fetched to say that we could create whole species if we are around for another few thousand years. That's more believable, but who created that civilization that created us? maybe another more advanced civilization and on and on. If that is the answer, that still doesn't answer the question as to what created the creator and what created the universe
When Science made the theory that you cannot create something from nothing, they were contradicting their big bang theory. When that was questioned the redid their theory, that the big bang didn't react the raw gaseous materials that made our universe, but it was an implosion from a previous universe. We know that our universe is expanding and gets larger in mass as a result, and will eventually slow down and should com back the other way until it implodes on itself, when looking at further galaxies at the end of the universe, they noticed that they are moving slower or are seeming to slow down compared to the galaxies closer to the center, indicating that the universe will turn around and re implode on itself. When trying to solve an equation regarding super-massive black holes and their time warp all real numbers came to an incomplete solution that in this case an incomplete solution was mathematically impossible since that outcome meant that the universe basically doesn't exist, when the term infinity was plugged in, the answer came out. They went back an even found the answers to other unsolved equations which worked. That equation in the sense of time played out to be:
Time has been and always will be
and
The universe is infinite (a phrase that had been used but never been mathematically proven)
and that's the answer to the universe, infinity. The existence of the gaseous materials has always been here, one big bang after another. And that is why in my belief that religion exists, the people who can't come to cope with the fact that there doesn't have to be a creator, that the universe has always existed as a reasonable answer, create the story of the skygod and call that a more reasonable answer than infinity. Any 3 dimensional entity in this universe cannot grasp or comprehend the concept of infinity and ultimately the ones who say that because they cannot comprehend that answer they will not take it for the truth are religious. But the thing is just because you don't comprehend a topic doesn't mean that the facts of that topic are false, it just means your brain isn't advanced enough to get it, and really no person on this planet really understands it, we just accept it. The ones who refuse to accept it, well you already know, create "Sky Wizard"
I will end on this note. I remember when I was maybe around 8-10 I ran this theory through my head its a very simple thought:
If you get in a time machine and go all the way back to the big bang, and you keep going back in time, will you ever reach the beginning of time? And naturally I came to the answer of no, you will always be able to go back in time forever and never stop (infinity) because time is an illusion to a certain point in the 4th dimension. My reasoning is that if you reached the beginning of existence, what happened before that? and the answer is, more time you can never stop going into the past regardless of when the big bang happened, you can always continue to get further away from it in the 4th dimension (either by the past or future), just like you can move as far as you want in the 3rd dimension, what happens, are you going to move so far away from the galaxies that you are going to hit a wall or a force field and even if so what is beyond that wall or force field...more space, because you can move in any direction forever, the universe is infinite, it has always been and always will be, yeah I may have had too much time on my hands before I started puberty.
In the end it comes down to whether you would rather believe sky wizard or infinity.
