FOR REINCARNATION BELIEVERS ONLY! MUST READ

I don't know whether something like this has ever came up before in the communities obsessed with proving or disproving the existence of a "Higher Being." What I'm about to state and show by example, does indeed prove the existence of reincarnation , if the information I'm using is correct.

From what I've learned, I've found that all multi-celled organisms should have a soul, so that includes insects,birds,snakes,etc and of course humans.
Correct?

Now lets assume that in the beginning, there were 1000 souls were created by the hand of the creator. As we all know, we move up in chain and don't start off as humans, so we all begin as animals. This sort of relates to evolution since evolution destroys and creates different species, which more or less has a balancing effect. Back to the main point, so we all start off as animals all 1000 souls, then years later 10 of those souls become human. The humans reproduce to have a population of maybe 50, so now there are 50 humans and 950 animals. As the human population increases, the animal population decreases. This is true since we are now in the process of wiping out certain species and we are also harvesting them for food. Our population is growing and that is a fact, and other populations of species decrease.

To prove if this were true, we would have to somehow get a total count of all the species existent on earth currently and maybe on earth 1000,2000,or 5000 years ago. If the same number of species exists in each of those comparisons, maybe differing by maybe 10-20% or a bit more but generally the same, then I think it would be safe to say that reincarnation does exist. To explain this 10-20% loss and increase, we can assume that these are the individuals who have reached "God-state" which would be like the angels, Buddhas, etc. The individuals who have reached this state and chose not to be reincarnated would indicate a decrease in the population size, and the increase by this amount might infer that they are returning to earth to help out.

It may sound like crazy talk, but if we were able to somehow get a count of the total number of species existent on earth now and before it might give us a whole new meaning to life, that is one without money and power.
