The universe is made up of time, space and matter -- what is called the
continuum.
The Bible says:
Genesis 1:1 In the beginning God created the heaven and the earth.
- In the beginning = time
- heaven = space
- earth = matter
Notice the triad of triads here as well?
- time = past, present, future
- space = length, width, height
- matter = gas, solid, liquid
For God to have created the continuum, He would have to be outside of it, else He is a part of the pre-existing continuum itself, and thus not the Creator.
You're limiting God to His own continuum -- a big mistake.
