>The unknowns:
>1. God exists physically or evidence of God exists and it is being deliberately kept hidden
GOD exists and "evidence" would violate your free will. You can choose to accept or not. Prayer is permission for God to affect your life.
>2. An entire human history exists that we know nothing about
Right. Read Ruth Montgomery's books starting with "the World Before" then read The less accurate books by Graham Handcock.
>3. The Earth is hollow (or flat or whatever)
Sorry, no.
>4. NASA has been lying
>5. Aliens exist
NASA Only lies about the aliens. Yes, they exist and are not a threat, although the AirForce does not like their ability to move around at will with impunity.
Read "Aliens Among Us" by R. Montgomery.
Borrow them through your library.
