If heaven was real, would you be disappointed to live eternally without any of the earthly activities that we have grown to love (videogames, sex, food, etc).

I think the concept of heaven is essentially a place that offers enjoyment beyond what we can comprehend here on Earth...so I would say no.

If Heaven was real it would be empty.

I won't be so disappointed I mean maybe we'll have some of the stuff you mention?

Sounds like a realm which can be more like a videogame you are in, than one you do now.  The immersion would be epic.

Of course, if you want me to speak of a Bible/Christian description of what would happen, the end is not going to heaven when you die, but a fusion of heaven and earth and God over all (Christian perspective, Jesus as Lord).  End result is a spiritual/material fusion actually, and not this stuff people buy into of going to heaven when you die, and all about with harps and halos and angels and clouds.

How do you know all that stuff is'nt in heaven? 

What if *this* is heaven?

What if we had some sort of living experience before coming to this world, and our reward for whatever happened was being able to experience this life?

I don't.  I guess I just meant according to the Christian Bible... I don't know.  A lot of Christians say that all they need is to be with Jesus, and I don't mean to sound blasphemous, but to me that sounds kind of boring for eternity.

If this life is heaven then I can't imagine what hell will be like.

If heaven was real I would go to hell.
