There are other religions that teach mankind will reside forever on earth. However, it is for good reason that few Christian religions believe this, as it is not supported Scripturally. See http://www.jwfacts.com/watchtower/earth-forever.php for a discussion on how the Bible when taken as a whole does not support at eternal earth.
How do you interpret the following Scripture?
Isaiah 51:6 "Raise YOUR eyes to the heavens themselves, and look at the earth beneath. For the very heavens must be dispersed in fragments just like smoke, and like a garment the earth itself will wear out, and its inhabitants themselves will die like a mere gnat. But as for my salvation, it will prove to be even to time indefinite, and my own righteousness will not be shattered."
I am guessing you have probably never noticed that Scripture, but will pull out the trusty old dismissal - "oh that one is figurative".
