I deleted your second part, because it makes no sense  

There is no such thing as "my theory" as i do not have it. Also definition of  "concrete evidence" may be different for you. Research, research, research.  Clear thinking, using common sense can help do the job.
If you are really truly curious, you will do your own research. You can start with fake moon landings and then come to the flat earth. Then maybe you will be ready to read the book of Enoch.

I wish you a fruitful journey.
