Technically, there is no such thing as an odd number. The reason why is because, you can split numbers. This might seem to break the rules of Mathematics, but however it doesn't. In real life, which is what Math is for, you are able to split items. In example, You find 1 cookie, and your brother wants a cookie too, so you split it, 0.5 and 0.5.

2 is an odd prime. A very odd prime.

If you are interested in learning/discussing math and science, a better approach might be to pose questions rather than post this kind of supposition. It's out of place for this site.
