Without any additional context that quote is just not true. Animals create their offspring, birds create nests, etc. But more fundamentally, God is conceptualized to be outside of time and space (nature). No one is arguing that a being inside time and space created time and space.

No mental gymnastics will change the fact that believing that no one created everything from nothing requires more faith than believing the universe was created by an intelligent personal being.

A painting implies a painter. Atheism cannot explain how we went from dust to a bacteria like organism with incredible complexity that was capable of reproducing without a whole lot of assumptions. It can’t explain how the non living matter even got here in the first place.
