Assuming there are no ghosts just because you can’t recreate your experiences in a lab doesn’t make it fact that there are no ghosts.
I’m going to need some explanation here because this sentence is confusing me.
You say you have experiences with ghosts. You say it may not have been ghosts. To say it was not ghosts, is not “fact” just because you can’t prove in a lab that it was ghosts. Science is content with saying “I don’t know”. Science doesn’t say “No, because you can’t prove yes.”
It is not a fact that there is no God. The “fact” is you don’t know.
You believe there is not. I believe that there is. Neither is fact.
