Do you think they did that over a period of say, 100 years, or do you think they had longer?

Do you know the difference between burning C-4 and hitting it with a detonator?

Burning C-4 is a slow process, burns nicely, reliably, under control. One can warm up, cook, it's useful.

Insert a detonator and hit it with heat and a shockwave, and you don't want to be near. The same thing happens as when you burn it, but much, much faster and it's dangerous.

To say that over the last 5 million years polar bears have faced extreme conditions is undoubtedly true. And they had time. Like burning C-4.

This is like detonating it, a different situation. You won't understand this, because it doesn't fit the world the way you'd like it to be. But anyone with a logical, rational mind who can tell time will understand.

There's a difference between events occurring over 100 years, and over a million years. Or even 500,000.

You see someone throw a hunk of lead at you and you can dodge it. Let them shoot it at you and it's a different situation.

So simple, and yet impossible for some to understand.
