To be honest all the conjecture and theories we all come up with is all who knows
We can find out the truth when we get to heaven and by that time I don't think it'll really matter one way or the other because all we're going to do is Marvel at the Creator
Well it s true that we will all know ne day the truth but we can know the truth now in according to His words.
Why is it necessary now? There is a pastor that does not believe in God any more because of the evolution theory. If he still does not believe in Him, I know not but back then when I was working with his son at a job, he had shared that family secret and how it bothered him and his mother. I left "The Collapse of Evolution" by Scott Huse at his home anonymously and hoped for the best.
So it does matter now.
I even had come across a former class mate that stopped believing in the Bible & Jesus altogether and he had left the Catholic Church & became a Buddhist because of the evolution theory. Fortunately the Lord used me to see the evolution theory as a false science and he believed in Him once more, but we had to part ways since he went back to the Catholic Church and did not see the necessity to narrow his focus on the Son as led by the Spirit to do and not have the Holy Spirit in focus at all when it comes to worship, fellowship or prayer in order to avoid the spirit of the antichrist that can come in and steal the spotlight even further away from the Son to lure them in chasing after them to receive for a sign.
I digress.
Anyway, there is an importance of going before that throne of grace for wisdom in understanding His words in Genesis as well as not see Noah's Ark as just a story as many scoffers do today especially when Jesus referred to that and Sodom & Gomorrah as real live judgments from God hat had happened in history for why believers are warned to be ready & be willing to go and not be desiring something from their lives to take with them or else be left behind.
Luke 17:26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noah entered into the ark, and the flood came, and destroyed them all.
28 Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;
29 But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.
30 Even thus shall it be in the day when the Son of man is revealed.
31 In that day, he which shall be upon the housetop, and his stuff in the house, let him not come down to take it away: and he that is in the field, let him likewise not return back.
32 Remember Lot's wife.
33 Whosoever shall seek to save his life shall lose it; and whosoever shall lose his life shall preserve it.
34 I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left.
35 Two women shall be grinding together; the one shall be taken, and the other left.
36 Two men shall be in the field; the one shall be taken, and the other left.
37 And they answered and said unto him, Where, Lord? And he said unto them, Wheresoever the body is, thither will the eagles be gathered together.
