This is a little hard to explain, so bear with me.
What we have to do is build a gigantic telescope in space, far bigger than the Hubble. Then we have to program it where it is always looking at Earth. Then we have to shoot it off away from Earth faster than the speed of light. It will catch up with the light that came from Earth, and in theory will be able to see Earth going back in time. Then record what the telescope sees then have it come back and we will be able to see Earth at its beginnings!
