For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness,
Here it says men suppress the truth. The truth of what? The knowledge about God.
because that which is known about God is evident within them;
This knowledge they have about God, Paul says, is evident within them. But how?

Through His creation, they themselves, everyone and anyone calling themselves an atheist has clearly seen His attributes, His power, His nature.
being understood through what has been made, so that they are without excuse. — Romans 1:18-20

You first sentence is a hypothesis. What evidence do you have for it?
All you wrote is a representation of dimensionality of space to convince us there can be something outside of space.
The fun fact is: There are no 2D creatures. There are no 3D creatures. We all live in space time. The whole "creature from another dimension" is pseudo-science. It is belief expressed with words to which you do not understand the meaning. It is the same thing as middle-aged women claiming "crystals have "energy"". Energy is a rigidly defined scientific concept.
