Last Updated:2011-11-04

1. No.4 is his house number is 913.

2. No.2: 23 people

3. no.5 - that is not a riddle, it is an argument of philosophy and religion. infinite regression.

but you can say that dinosaur eggs exist prior to chickens.

if you mean a chicken egg then a chicken which we know of todaythen the genetic mutation would have to exist in egg form before any other form

4. Chicken egg question is not really a riddle, though an egg contains a chicken within it, so even if the egg came first, there is also a chicken developing inside. It does also make sense to say dinosaurs payed eggs, but I think the question originally referres to a chicken egg

5. no.2 is anyone born on february 29?
