Given a materialist view on things (the mind cannot exist separate from the body), it seems on the surface that an afterlife is possible. However, the SEP entry on afterlife seems to provide some pretty good objections to this idea. How can any of these problems be surmounted for a theist? One of the objections is this: if God created multiple beings the same as the one on Earth, how would our consciousness be preserved? This question is not asking if mind-body dualism is right or wrong, rather I'm asking whether afterlife is possible given materialism.
Edit: When I say "materialist", I mean the idea that our bodies go to heaven with our minds, not just our minds "by themselves". And this question is mostly aimed from a Christian perspective.
