Could infinite God create infinite universe?

[narnia4]

Just to clarify, I was thinking mainly of Aquinas in another thread when I said that theologians and philosophers in the past did not depend on a beginning to the universe. And of course there were some who actually believed the universe was eternal. A few famous Islamic theologians who followed Aristotle come to mind.

[7] Furthermore, if the world always existed, it will follow that there exists an infinite number of things, namely, the immortal souls of an infinite number of human beings who died in the past.

This, Aquinas says, is the closest to a convincing argument. The idea is that if the world was beginningless, then there would now be an infinite number of souls in heaven, but that is absurd (because now we are dealing with a proper infinite simultaneously existing in the present). The problem with this argument is that it just takes too much for granted that the skeptic is not likely to accept; indeed, it is based on premises that are known by faith! For instance, why should we accept the notion that the soul continues to exist after the body, or that if it does, it continues to exist forever after the body (that is, why should we accept the immortality of the soul?). On the other hand, someone could come up with counter proposals to explain away the requirement such as a beginning of the universe, such as reincarnation. We don't believe in reincarnation, but that (again) based on faith. So whatever truth it has rests on premises that cannot be embraced without embracing still more controversial or at least faith-based premises.

I do not see one thing here. Why in the beginningless world there would be an infinite number of souls when we assume the notion that the soul continues to exist after the body? Isn't it possible to have a universe without beginning but people in it having beginning and souls having beginning? Couldn't God create it that way?
