“We should qualify the prediction by stipulating that if any sign of life is found, it will turn out to be remnants of Earth life that somehow got transported to Mars, perhaps by a glancing meteorite.”
The way this is written, I wonder if the author thinks there is no life in space anywhere. Does the bible claim Earth is the only planet created for life?
No. I've often wondered about this. How logical is it to assume that God would create a dead universe?
