Yeah.......may have been is a real scientific term. Yet.....science proves that even the highest points on earth were at one time UNDERWATER.....more evidence than your "MAY HAVE BEEN" for evidence of a global event.
You either accept the truth recorded in scripture........or you dismiss it as a humanist. Thus far.......nothing but OPINION, CONJECTURE, SPECULATION, ASSUMPTION AND BIASED OPINION have been submitted as evidence that the Bible is not a history but a book of analogical myths. Why? No one enjoys being convicted in their sin.........its a matter of self delusion. Its hard to sin when you tell yourself there is no GOD, and no GOD has ever communicated HIS WILL to mankind.
Misery indeed loves company. Thus the truth as found in scripture, "Not everyone who says to Me, 'Lord, Lord', shall enter the kingdom of heaven, but he who does the will of My Father in Heaven. Many will say to Me on that day, 'Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?' And then I will declare unto them 'I never knew you; depart from Me, you who practice lawlessness." -- Matt 7:21-23.
As for me personally? "For do I now persuade men or God........Or do I seek to please men? For if I still pleased men, I would not be a bondservant of Christ." -- Gal. 1:10
You can seek to PLEASE MEN.......as for me and my household.....we shall serve the Lord.
