Are you sure?

I'm absolutely sure.  Are you not familiar with the geographic structure of the Earth?

Not really

Why not?

I just don't know much about it

Well, there are some things I could explain to you.  But you’d have to really want to know about them, and have a sincere desire to understand.

You have to go back into history, and the history of the Earth.  Look at these points in time:

-   the first single-cell organisms
-   the first complex multicellular organisms
-   the first vertebrates
-   the Cambrian explosion
-   the first apes
-   the first apes to leave Africa
-   the first farm
-   the first astronaut
-   the first satellite
-   the first human
-   the first time zone

I am happy to.   Here is a map of the Earth.   In the upper right hand corner you'll see a red line going downwards.  That is the Earth's equator.  The closer to the equator you are, the hotter the climate will be.  It will be much more difficult to survive at the North or South Poles.  What sort of climate would you like to live in?
