Sure it is.
If God did will existence into reality, then what He created is tangible and can be used as evidence.
Can I use something you created as evidence even if I didn't know you were the one who created it?
I disagree. There are two theories about how life was created. One is the creation theory, the other is spontaneous generation followed by evolution. There is honestly no evidence presented for EITHER position. There IS evidence for evolution, we have actually seen it happen, but for the spontaneous generation aspect there is zero evidence.
The fact that we are here as people, is not evidence for the creation theory. It is evidence of the evolutionary theory, certainly the fact that our DNA is so close to chimpanzees
reinforces that line of thought. But, yet again, who's to say that a God didn't start the spark of life, and then sit back and see how the experiment turns out?
That's the problem with the arguments, any bit of evidence that you present to support the existence of a God, can likewise be used to refute it.
