"Christianity ... sent a man to the moon."

Clearly you have never read "The Right Stuff" by Tom Wolfe.

The United States has always done best when run by atheists/deists:

Franklin; Jefferson; Madison; Lincoln; Teddy Roosevelt; FDR.

It has been in steady decline ever since Ronald Reagan welcomed the religious cultists back into the White House.

No religion has done more damage to America than evangelical Christianity.
