The question is What Type of challenge?
Once you realize that gods and religion are both human creations that are not based on anything that can be proven REAL - that is not a "Challenge to faith" that is " acceptance of reality".
A challenge to faith might be a loss of a loved one - or something that happens that does not appear "right" in the ways of your religious belief - of which you can generally decide that there is an Evil force in the religion that can be called responsible for it.
However - Santa Claus is not real - neither are gods or devils or angels - all creation of humans. Once you actually read the bible - and understand how inglorious and downright stupid it is - and how the claims of it being infallible are nonsense - and then realize that prayer has NO effect (All people die - not ONE prayer has EVER worked - even the christ supposedly died although it could not have) - THat is simply acceptance of reality.
SO when religion says to you that the earth is the center of the Universe - we KNOW that is false. When they claim Adam and EVE- that is a MYTH - not reality. THe talk of a great flood never happened. ANd the christ is - at best - an exaggeration - if not a total fraud.
