Infinity and Moses

The one interesting thing I did read today was regarding Moses and Abraham. The suggestion was that we can be sure that they where called by God to do what they did, but we can't be sure they where the first to be called. Is it not possible that God may have tried to persuade others to undertake the assignments, but through stubbornness or fear they ignored the call. Perhaps Abraham and Moses weren't called because they where spacial, maybe they were special because they heard the call and gambled. I'm not sure. The same book also pointed out that in the Bible Moses was ''the most humble man in the world''. Now assuming that were true, then that would be reason enough to go straight to him. However in Abraham's case, It might not be so clear cut, and perhaps he may not have been the first.

I was also thinking about infinity. As far as I understood it, infinity was......infinity, that was it. Whilst it is not a number, it is a concept and I would define it as something without end, numbers being the classic example. Google definitions suggests int may be ''time without end'' but I don't know how that definition can be reconciled with numbers. But it would appear after some preliminary research, that there may be different levels of infinity, but does that mean different levels of ''Time without end''?......

I don't get it.

The theory as I understand it goes thus; There is an infinite number of whole numbers, I believe that would be undisputed (although I would like to see a proof). However, between the first two numbers (1 and 2) there would be infinite amount of irrational numbers, as there would between 2 and 3. So the thinking was, if you tried to match up all the irrational numbers with the rational (whole) numbers, you couldn't do it. Hence there are different levels of infinity. This has been put forward by smarter people then me, but they don't have blogs so I feel free to challenge it. At first glance it would seem true, but the whole concept of infinity is such that you couldn't 'match' any infinite item up with anything else, it surely can't be done. Does that mean that there are infinite levels of infinity? Well no, because then infinity would just be another word for a ''number'' as the same is also true. I hope I'm not coming over as a smart ass here because I genuinely just don't get it.

If anyone has any proofs for why there are infinite numbers, I would love to see it.
