Plate Tectonics - 4.6 Billion Years in 5 Minutes

Some of the things we know, and don't know, about plate tectonics.

Even if you believe god created it, it certainly has changed a lot since then. In fact, it's changed many times and continues to do so.

When viewing the split up of the super-continent of Pangaea into the world that we would currently recognize on a map, take note of India. you will see it racing up the Indian Ocean from Southern Africa to slam into the Asian continent. This is what created the Himalayas (one of those things I mentioned that we DO know).

I love watching stuff like that. Do you know what program that was?

I contacted the guy who posted it on YouTube but haven't heard back from him on it.

Here I am sitting on a molten, radioactive, plate shifting piece of crusty filmball, whirling thru the universe at an ungodly speed; thinking that everything is OK. Talk about denial!

Sillysighbean,

May be such a thought is hardwired into our brain. The hope that everything is fine and perfect. And this can happen to everyone. For instance, we hope that a football / a cricket team, we support will somehow win the game given any abject situation though our proper senses tell that is almost impossible.

And I think it will take years of evolution to change such a thought.

I don't know that it would ever change. Unless there is some survival value to the mutation (which, of course, there could be in the modern world we've created).

The good thing is, we already have what it takes to overcome our genetic predisposition for accepting gods. The same level of self-awareness that causes us to seek (and create) explanations, can allow us to accept other ones that are more firmly grounded in reason.
