An actual infinite is an absurdity.
Why so? Does space have a boundary of is it infinite?
You need to rewrite the second question. I'm not sure what you're asking, but it doesn't seem that you understand what an actual infinite would be. Only potential infinities exist. God is not the concept of an actual infinite either, by the way.
What is the numeric value of infinity, precisely, in terms of mathematics and magnitude?

Didn't the laws of nature exist before our universe and our universe created within the existing laws of nature?
The laws of logic and mathematics are incontrovertibly true, but you don't believe that . . . except when you unwittingly do, when you assert anything intelligible, that is, anything discernibly true or false. The laws of logic and mathematics tell us that the laws of physics existed prior to the existence of nature. The physical world was created in accordance to and is bound by the preexistent laws of physics.
Created within may be interpreted to mean something nonsensical or absurd.
Was there ever a time or place where 1 + 1 did not equal 2?
