Noah's flood seems to be a myth to those who do not have faith in Jesus.
Maybe if He returns in Judgment, that will be enough evidence for these naysayers. This may happen very soon, maybe this year. God destroyed the world once with a flood and will destroy it again, but this time with fire. When Stephen Nye is thrown into the fire, he'll suddenly have and epiphany, there is a God and He's angry.
People choose to mock the Bible, disprove it, exchange it for their evolutionary ideas. But fundamental belief in Jesus does not require us to believe in an old or young earth. We believe in Jesus for who He is, what He did and said and what He will yet do.
Prophecies fulfilled with hairsplitting accuracy exist throughout the Bible. Jesus fulfilled hundreds of them. This is one primary reason why people believed, because Prophets came along and said stuff was going to happen and it did, otherwise they were stoned to death if they were not 100% accurate. Now obviously, they had to prophesy about things within their lifetimes to prove they were messengers of God. But they spoke of things well into the future, things which are happening right now. Israel becoming a nation after being scattering throughout the world for over almost 1900 years is prophetic. It is in this generation (70 years), from 1948 that we have seen prophecies of the end times fulfilled and we are getting close to the end. Jesus said there would be wars, famines, pestilence, earthquakes in various places and this we have seen increase in frequency. These are the beginning of sorrows.
Even more specifically, a sign that the end is near was spoken by Jesus in Matthew 24:14 where He said, "And this gospel of the kingdom will be preached in the whole world as a testimony to all nations AND THEN THE END WILL COME." This has just about been accomplished within the last couple years.
When this begins, the whole story of the origins will be a mute point won't it.
When the events foretold in Revelation actually begin to take place, fear will wet in to those who have no faith. Stephen Nye, Stephen Hawking or Richard Dawkins will be speechless. Oh yes, they won't be discussing origins or mocking the Biblical narratives.
And what if Revelation 12:1 really happens on 9-23-17, will that be enough evidence?
When they see Jesus coming in the clouds and the bible says every eye will see Him, will that be enough? When 1/3 of the planet is on fire, will they get it ... or will they just pass it all off as natural or man-made?
