Is it possible life didnt start on Earth?

Recommended Posts

...that the building blocks of life are EVERYWHERE in the universe. In the dark void. In the solar winds. Perhaps in suspended animation. It just so happened that the other 8 planets are dead worlds.

Whereas the seeds of life couldnt take hold on those desolate worlds, Earth was the one where it could flourish. That this same process is going on in other exo-solar systems? 

Its possibly nothing special about Earth, and that the seeds of life are all over space, the other 8 planets being unsuitable.

Are you familiar with the Miller-Urey experiment?

and equivalent experiment of making RNA and DNA building blocks?

To create adenine you just need 5 HCN and electricity e.g. thunderstorm.

It took billions of years after the first single cell microorganism appeared on Earth, before they began to cooperate in a multicellular form of life.

Earth like planets with existing life forms might be extremely deadly place with unknown lethal pathogens.

Still favor Theia myself, but multiple options are possible.

Either starting from one or multiple locations and spreading or each planet/moon/other having their own seperate beginnings of life.
