The argument turns on starting points. By beginning with a given, that man exists, all of the necessities resulting in that given become consequential, not subsequential.
Betty boop, on another thread, is discussing the problem of time relative to quantum mechanics and etc. If time can be viewed in reverse with the present as the cause of earlier events the question of necessity for the existence of life is answered.
I have long felt (intuited) that the present does not just inform the past, the present determines the past. This is not so far fetched if we imagine that the universe is in its contracting phase and is running in reverse.
This line of reasoning is in keeping with the omniscience of God who must view all time in an instant. Whether creation is run forward, backward or as a jumble is incosequential since it all comes down to the magnificent surdity of now. This is all we know. Everything else is conjecture.
Every time you look out the window, you are peering into the past. Look at the moon and you are seeing how it was a few seconds ago, not at how it is now or a few seconds into the future. Intuitively, it would seem that time is running forward.
If you theorize that light travels at infinate speed then you can picture the entire universe as a traveling wavefront of a 4d sphere expanding. The reason light appears to have a speed is that every point has a different 4d vector with your perspective being your vector is now and every other vector being behind you. The farther away, the more the vector is pointed away from you giving the illusion that is is farther behind.
With this view point, there is nothing in the past or future, just void that has seen the wave front or will see the wavefront.
How’s that for mind bending?
