if you was to lie down at noon so you were facing the sun, then go out in six months timeand lie in the same place at the same time, would you still be facing the sun.?
if the earth rotates once every day and goes around the sun once every year. then surly you'd be facing away from the sun the second time you did it.
if you don't understand this simple thing then get two balls, put a mark on one(earth),so the mark is facing the other one(sun).now rotate the earth as it moves around the sun and you'll see that when you get half way around, if you have done a complete number of turns with the earth, the mark will be facing away from the sun.

If the clumps of hair known as eyebrows are there for eye protection, what purpose do the clumps of hair on other parts of the body serve. There seems to be no logical explaination.

Science claims that the current species of mankind, the Homo Sapiens appeared about 90,000 years ago in Northern Africa. Humans have evolved on a constant basis both in skeleton structure, skin color, and regional characteristics. Where and what will happen to us next?

Ok... does carbon dating take into account that all the elements that are on the earth are the same elements that were originally created or "banged" or whatever? (per the law of thermodynamics which says (I think it's the first) "matter can neither be created nor destroyed")

I guess what I am trying to ask is how can you tell one tree is older than another through carbon dating if they are both made of carbon and oxygen and hydrogen atoms that have been around for the same millions of years?

Do I have the wrong idea about carbon dating in general? Does it only apply to certain things... and also when you like, do it to a skelton, does it tell you how old the bones are or how long the person has been dead?

I am very confused.
