Had you had a thought or thought of something and just like that your mind Erase it? and you cant remember what it was at all.

Why does are Mind Erase that thought? how does it do that? where did it go?
Is it still there somewhere? Is it mind Overload? Sometimes but rarely it comes back.
Is it the resuit of time travel? without us realiseing that and the thought dispeared.

Did God Erase it for us? even though it was not a bad thought. Was it just best for us to have had that thought erase?

There are medical-scientific explanations, including aging. The thought is still there, just not recoverable. It has to do with electro-chemical processes at the synaptic cleft in the brain. I would say that it is entirely mental, not the spiritual result of God's censorship. When I have a thought that I should not have, as a Christian, I confess it as sin, receive forgiveness, and enjoy restoration of fellowship with my Savior. 1 John 1:9.
