Why?
They boomed up.
They did?
Uh huh.
Well, we don't really know why but we think a big meteor crashed into earth and changed the climate.
What's a big meteor?
A big space rock.
What happened when it crashed?
We think it crashed and exploded.
Mom, that's why the dinosaurs boomed up they got caught by the sun.
Did you know the sun is a big ball of fire?
It is!?
Yes.
Mom, when I get big and grow up to be a spaceman, I'm going to go up and look for cracks.
Are you expecting cracks in space?
No. I'm going up to look down for cracks.
Oh, you're going to go up in space and look down on earth for cracks?
Yes. And when I grow up and get big I'm going to dig real deep in the cracks and find HUGE dinosaur bones.
Some day you just might buddy, someday you might.
