Archy Laura and her Daily Cup of Tea

You know how you can't technically, as we know it, seperate space and time? like, if you were looking at a galaxy 4 million light years away? and what we are seeing is the light from those 4 million years ago? well.... sure all we can see is light, but what we need is some crazy super high tech scope or device that only my imagination can conjur, that can zoom right into these distant galaxies (like we do now) BUT, also into planets and zoom right into the planets themselves to see! or something like that. The idea is what is important. Then what we do, is figure out worm holes and go to that destination at the same time it is now, 4 million light years away. Now we will be looking at light coming from earth 4 million years ago!  and we simply go opposite and zoom into earth! and then we can see what life on earth was like 4 million years ago! or whatever time frame you desire.
....back to my secret lair, I go!
