Did the Christian God ever allow any Neanderthals in to Heaven?

No one who died before Jesus Christ would go to heaven.

I doubt Space God would do it, but since he's not real, it doesn't really matter.

A person can better know the difference between truth and fiction by reciting the rosary every day with care and sincerity.

It truly does not matter. 

If "streets of gold" … "mansions in the sky" ...  

and brokered salvation were not in play, there isn't a 

christian alive who would know what to do with themselves. 

Their "christian" god turns good & decent people into beggars. 

if they had a conscience then they were able to go to the Happy Hunting Ground. But when man evolved a Collective Conscience he began to understand LOVE and GUILT they could very well end up in Hell until they decide to learn to love everyone unconditionally ; as Cain could've .

Well, FB says that Neanderthals were “not real”, so I guess that takes care of that. All the Neanderthal fossils are fake. 

Neanderthals are humans that inbred due to their isolation in the glacial North.  Let it be a lesson.

THEY WERE NOT REAL...ADAM WAS THE FIRST REAL MAN!!

He was invented after Neanderthals had all died out.  So they don't count.  A lot of things have been conveniently left out of the liturgy.

Not sure, but what are your thoughts on yourself?
