If all the water flooded the earth it would raise too high in altitude, and the world would freeze.

It would be stuck like that.

Also

Where did all that water go?

Did god just 'make it disappear'

Or was there a gaping hole in our crust from the mantle?

The loss of water in the crust would destabilize the crust and cause massive collapses to such an extent that massive creators would have formed globally.

Craters*

And agreed.

Meaning that many, if not all, of the continents would have caved in on themselves and wouldn’t exist.

Honestly, I think it was from when all the ice caps melted, and it covered a large portion of the world, as not every ancient religion has a story about a great flood.

That is most likely it.

It was mainly eastern and middle eastern religions, too.

The water just went back under the crust to the mantle. And you’re assuming that Mount Everest has always been there. It was formed from the crashing of the plates. The water level wouldn’t need to be high enough to cover a Mount Everest.

Genesis 7: 11 In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.

12 And the rain was upon the earth forty days and forty nights.

The death on this global flood scale is most likely where our fossil record comes from.

But every mountaintop was covered in water, or else he would have been able to find land.

The mountain tops were created as the separation was calming down. He could just as likely landed on Mount Everest or the Rocky Mountains or even the alps. His boat just landed around modern day Turkey most likely.

Pangea was ripped apart to let the water out from the mantle. Then as everything settled, the water went back to the mantle and the plates continued to move.

And if we all came from 1 family, how come we all look differently

Different races.

Genetic variance is huge. That’s like asking why all dogs don’t look the same.

No

You have a family of 8

Race would be an appropriate term if we couldn’t breed with all humans.

They all look relatively similar

Besides

Black skin is a dominant gene.

We would all be black if that was the case.

No. We’d all be brown. More like Arabs or Indians. But the people groups separated at some point. This is supported by migration patterns.

But it was a family of 8

There would be massive amounts of incest.

Which technically we’re all brown.

I'm white.

Lol you’re brown. Just very light brown. 🤣

Regardless

We all have melanin nigga lol

I’m as white as you are

If I came from Noah, I would be a huge incest baby.
