If the mechanisms of evolution are just imagination, then isn’t religion also just the imagination of some sages?

From Vinayak

A comment of yours from the article ‘atheism refuted’: “And even if somebody could imagine some mechanism involving natural selection by which certain complex features in some organisms came up, that doesn’t at all prove that it happened that day. That is imagination at work, not science at work.” – Well said, then pray tell, why don’t you say that the Bhagvada Gita and the entire Hindu philosophy was the combined imaginations of a group of really clever and intelligent sages? Maybe all the Hindu, Christian, Islamic Gods are nothing more than the imagination of clever humans!
