Life Eternal

 If religious people believe in eternal life, then what is the real purpose of life here on earth from some 80-90 years?

The average life expectancy in the US is 78.87 years...  (2019 data)  However, on average people live longer in the UK 81.16 years.

So, if you are a religious person, then you can spend (ON AVERAGE) more time here on earth if you live in the UK than if you live in the US.

That should please religious people...  RIGHT?

If one had to ability to read every single book that was ever written and/or published regardless of language, then one would be able to easily surmise that the purpose of life here on earth is 

SURVIVAL,

and, if this is the case, then religious beliefs are only good for life eternal...

Life eternal makes more sense anyway after the concept of survival is fulfilled because it seems completely ILLOGICAL for mankind to live 80-100 years IF all that happens to them after they die is that they are simply put into the ground or cremated.

It is also highly unlikely that mankind is the only living race of people in our ENTIRE UNIVERSE...  especially since there are over billions of billions of solar systems in our UNIVERSE.  Unless I am mistaken, that's PRETTY DAMN LARGE.

And...  if you are a religious person then you will use your basic instinct of SURVIVAL to live as long as you can on earth so that you can DIE and live for all eternity in a location called HEAVEN...  As illogical as this sounds, it makes better sense than just dying.

FURTHER, in every single Global religion there is a GOD or some form of superior being around which their religion revolves...  this cannot be MERE COINCIDENCE...  the question is whether or not this is God or some form of ANCIENT ALIEN...
