Here is my view on the matter and remember I am Mormon and I am a devout follower of my religion.

Everyone must accept their religion in their own time and it can't be forced on them. To force anything on anyone will only indoctrinate them against what they are being forced to accept. I see so many youth in my church that rebel just out of the fact that they are being forced into something they should have been allowed to accept within themselves.

The story of Noah is quite interesting when you delve into archaeology and find that an immense flood once covered the earth just by the composition of the rock in certain layers of sediment. As for the animals on the Ark that is more plausible when it is found that most animals around that time were alot smaller than the animals now and days for instance it is believed that the Giraffes neck was about five to seven feet shorter then than it is now.

My view is that eternity is a long time to have been mistaken in life and whether you believe in God or not imagine what would happen to you "IF"...
Anyway I am glad to hear that the child can accept her own religion within her own time.
