Take a look around you. Everything is subject to the incredibly vast science which we use to continually develop, improve and understand our world.
Oh so VERY true, now it should be a very small step for you to understand that the principals behind this science was created / was there before the scientists started disecting and investigating and publishing "How things work" - very good work I might add (in some cases).
science is far better on the 'hows' than the 'whys'
see above
D/ Obviously any planet we were going to immigrate to would already have life on it otherwise it would be pointless to go there in the first place so it would not be necessary to take every species that are here on our Earth.
just take a few Aussie (or NZ) quarentine guys along and NOTHING will go :)... It's always amased me though how Aussie troup are able to take their pets to OS locations... birds, dogs.... surely the same dangers exist for them?
