Another thing is all these years of debate and arguing over who's guess is actually correct...has gotten us no closer to any concrete answers. Just a big unproductive circle...with all parties holding one another back.
Reminds me of a captured alien space ship complete with a instruction book...and everyone too busy arguing over who really understands the instuctions and should be appointed to drive it...to actually admit ignorance and come together, work together till understanding is achieved.
Then worry about who should drive...perhaps then everyone could drive!
But maybe that is the whole problem....everyone wants to be superior to everyone else instead of pursuing equality instead.
