I'm not getting it. Assuming we accept occam's razor, that argument has nothing to do with god or anything like that.
It's irrelevant to say that we can explain the existence of religion through environmental factors. Because whether or not these people believe in God, and why they believe or don't believe in God, is not indicative of the truth of God. If you're trying to say that there is a connection, and that these people believe based on bad reasons, and try to deny the existence of God based on that, then that's an ad hominem argument.
