I've wondered this for many years: could the idea that life originated here on Earth be the final geocentrism?
This is really quite interesting too:

All this is pure hypothesis and speculation until we can find some life out there and engage in some comparative analysis. If we found life elsewhere and it appeared to trace back to a common ancestor, then this would suggest that life originated far back in the history of the cosmos rather than independently in many places. Perhaps life -- if interpreted as a phase of matter -- arose along with all the other phases of matter during the early cooling of the universe?
