@Theaetetus,
It is interesting how one can cite the
theory of relativity to prove their point and then attack someone for using another theory, of evolution, and do so using outmoded Darwinian evolution. Go read John Archibald Wheeler's writings on the idea of reversible and non reversible processes, and don't cite the theory of relativity unless you can understand an accept the physics behind it as likely rather than absolute. There are no laws of science, only likelihoods. A law would imply that induction is absolute truth, this is false for we do not know of all possible events, we only draw up a theory by what we see.
Assume god created everything. God is then not a thing unless god created himself. God created existence, thus god does not exist unless he created himself. Our minds are a product of god thus any conception of god which we have was created by god. Our universe is not self causual thus not of the same nature as god. Take that as you will.
Assume that god created our physical universe. You argue that our physical universe (perhapse the multiverse conjectured by Mikio Kaku) is not infinite for time is not infinite as defined as the distance between two physical events. However, you assume that time is not infinte by stating that you cannot concieve of it and a man cannot do it, thus god cannot do it, assuming god has the limitations of man while claiming that he has no limitations, a contradiction.
Further, assuming god caused himself is not in contradiciton to any assumptions made in this thread. God created the physical universe and all that exists, god is caused by god, thus existence is caused by that which is caused by itself which it god. Since god is eternal and self causing, surely then so can be the universe?
Pick that apart, I'm not entirely sincere in the argument but I would like to see it refuted.
Edit:A good objective measure of species is interbreeding, it has been suggested that classification be genetic based upon whether an animal can interbreed with another. There is still the problem of classifictation by physical appearance. A dual classification might not be a bad idea.
