Hello eternal life granted to humans through salvation has nothing to do with heaven because it is the true gift that God rewards humans with for life on earth forever, Romans 6:23.
The ability to obtain eternal life goes hand in hand with deep and profound intelligence which will serve you well in the eternal years that you will live. You won't get bored and just sit around thinking of nothing since that is the lives that imperfect humans live, 1 Corinthains 2:9. God promised us salvation and there are many things to go along with it. To live billions of years is not a hope our parents could have dream of, since it is not a human prospective. It is truly a gift that God would grant to us and will surely make us different humans, Children of God.
1 John 3:2
2 Dear friends, now we are children of God. We have not yet been shown what we will be in the future. But we know that when Christ comes again, we will be like him. We will see him just as he is.
