All true! My point was that should I go back in time to 1400 and alter the timeline, Columbus might never set sail and discover America. However, that wouldn't stop America being there, and someone would discover it at some point, and people would cross the Atlantic and settle there. I can still tell people that without knowing precisely when, but they may not believe me. Man would still walk on the Moon one day, but they probably wouldn't believe that either.
I do understand what you're getting at Dave. I was just taking the premise a little further, in that with the changing of the timeline we shouldn't just look at how we could affect it.
For instance, I agree the land mass we now know as America has been in existence since the beginning of the Earth (albeit constantly changing). However if you stopped Columbus discovering this land mass, then yes somebody else may discover it. The likelyhood then is that it may not be called America!
Also that countries development may go in a different direction and the moon may not be in the sights of anyone to 'conquer' for centuries. However, a lot can happen in centuries. A stray comet may hit the Earth and we all die; so no one walks on the moon.
To take it further, and keeping with the Star Trek Universe, what if another more developed race/planet, altered something that caused the above mentioned comet to hit the Earth sometime before man even roamed the Earth. Then everything you stated would be incorrect as it wouldn't happen.
However, I am aware that the points I have made also mean that everything I have said is subject to 'change' and the same Temporal Paradox . Maybe the comet didn't hit Earth, and whoever discovered America could have called it such, and that the countries main drive could have been to land on the Moon.
Temporal Mechanics, you've gotta love it!
