Again, if there is a no evidence of a creator, why do we create or give birth?<quoted text>
Well, we are here and there is no evidence of a creator, so we came into existence somehow. The evidence supporting how humans evolved from another species is in the fossil record, and our DNA. It's quite a complete collection, more evidence than I have seen for ... well anything, ever. Even more evidence than what we work with for how computers operate, ironically. I am still learning about the evidence for human evolution, and I doubt I will learn all of it, much lest get the chance to test most of it, in my lifetime because of how much there is, but it's there. You will deny the evidence, simply because you don't want to see it.
So I ask you again, where is the evidence that there is a creator?
You can not rule out that possibility.
