I saw this video recently, explaining how there are older flood stories than Noah's Ark.
I won't spoil it, but its basically like Noah's ark is deliberately referencing other flood myths.
Which got me wondering, do you think it matters for Christianity if the flood didn't happen? Because a lot of my conservative friends think you might not be a christian if you don't believe Noah's ark happened (that's a slight exaggeration).
VIDEO (5 mins long, entertaining)
