Are Rainbows Proof that God doesn't Exist?

We all know the traditional bible story of the rainbow; that it’s a symbol that the flood is over and the evil has been washed away, and that it’s God’s promise that it’ll never happen again. But how many rainbows have you seen in your lifetime? Perhaps Christians argue that today’s modern rainbows act as a reminder that although this flood was heavy, it wasn’t as big as the one as Noah faced in Genesis. But if you actually read Genesis, you’ll also learn that Noah had three sons at the grand old age of 500, and died at the ripe old age of 950. Quite amazing for today’s standards, especially as we now have better infrastructure to cope with today’s modern flooding. As sons of Noah, we certainly have filled the earth as God commanded; but it’s a strong test of faith if we are really to believe Noah’s story.
