If you could time travel, would you rather go into the past or the future?

I have this fantasy about seeing my home town and present town back before Roman times. Long before the Saxons invaded. Something like 4000BC would be interesting, just as civilization was beginning to spring up around ancient Mesopotamia, India and China.

I suspect it would mostly be forest with a few small settlements here and there. Nevertheless it would be fascinating.

I also think ancient Lemuria and Atlantis civilizations that were destroyed long ago would be amazing too see especially as we still have very few tangible physical evidence they actually existed. They were supposedly far in advance of us both spiritually and technologically.
