Levh-i Mahfuz

Before all the visible and invisible worlds were revealed, was it written in a dimension, like a tree’s seed?
If it was written, what kind of pen was it written with?
If it was written with a pen, what kind of pen was it?
Who wrote it, what was it that wrote it?
How did the universe or universes come into being, how does it work, where does it flow to? Are there codes for the existence and functioning of the universe? What are the subtleties of the dimension of Mathematics, Physics, Chemistry, Biology in the creation of the universe?
