Yet Jesus Himself gives it total credibility:

"But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father. As it was in the days of Noah, so it will be at the coming of the Son of Man. For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man. -- Matthew 24:36-39

So, the second most important thing he has promised to do is "just as it was in the days of Noah."

On the one hand you claim that some miracles are "too small" and have some natural explanation. But it they get "too big" then they are "laughable".

I'll double down on you. There was a point in Joshua where the Lord stopped the earth from rotating (without sloshing the Atlantic ocean across Africa at 1000 miles per hour). No problem. He did just for Joshua's convenience in winning a battle. (Joshua 10:12-13.

And in another case he made the earth rotate backwards (without spilling a drop) just to provide an impossible, supernatural sign for King Ahaz.

This shall be the sign to you from the LORD, that the LORD will do this thing that He has spoken: 8"Behold, I will cause the shadow on the stairway, which has gone down with the sun on the stairway of Ahaz, to go back ten steps." So the sun's shadow went back ten steps on the stairway on which it had gone down. -- Isaiah 38:8

Laughable, right? Unless you understand that God has the same kind of control over every particle of this universe as if it was a simulation that he can simply, pause, rewind, or even restart at any point in time.
