Logic Riddles

Question: An archaeologist is searching some caves and discovers two frozen people that have somehow remained completely intact. He immediately recognizes them and knows that they are Adam and Eve, the first two people.

How did he know this?

Question: An ant gets onto one end of a tight rope that is 1 meter long. The ant is traveling at 1 centimeter per second, but the entire rope is being stretched an extra 1 meter (1,000 centimeters) a second (it can be stretched forever).

Will the ant ever reach the other end of the rope?

Question: A group of ten people are going out for pizza but only two of them have an umbrella to keep them dry. But they manage to walk all the way to the pizza place without getting wet.

How is this possible?

Question: A man is walking through the park one day and sees a group of four boys standing in a circle. A smaller boy is holding a large stick and hands it to a larger boy saying "I couldn't do it, your turn."

The larger boy swings the stick twice and the other two boys go to the ground. The smaller boy says "I'll get 'em next time." The man walks away smiling.

What just happened?

Question: Ants on a stick may only move left or right. If they bump into each other they bounce off of each other and immediately move in the opposite direction maintaining speed the entire time. The only time they change speed is when they fall off of the edge of the stick.

If 25 ants are randomly put on a 1 meter long stick moving 1 meter per second, what is the longest amount of time it could take for them to all fall off?
