It is known that the only place in the universe where living beings exist is on planet Earth. Does it mean that life originated on our planet? Do you heard about The Panspermia Theory?
A theory suggests that this is not the case and that life on Earth could have come from somewhere else in the universe and then ended up here.
It is known that the Alpha Centauri star is a little older than the Sun. This means that it was born much earlier; being so, would it be possible that life arose first on Alpha Centauri and then those living beings ended up here on Earth? What does science say about this hypothesis?

Did life originate here?
Although evolutionary evidence suggests that all living things on Earth arose here from other simpler organisms that evolved over billions of years, we still do not know exactly which was the first living being.

Fragments of other worlds
In a past video, we talked about the possibility that there are dinosaurs on the Moon, and while that may sound wild, it isn’t. If you haven’t seen that video yet, we invite you to watch it.

Extremophile Organisms
One of the leading proponents of the panspermia theory was the British scientist Sir Fred Hoyle, who proposed the idea in the 1980s. Hoyle argued that the complex organic molecules necessary for life could form in interstellar space and then be transported via comets or meteorites to suitable planets.

Omuamua
With an elongated shape and unusual motion, Omuamua is the first confirmed interstellar object to have visited our solar system.

Are there exoplanets in Alpha Centauri?
The idea that life could have arisen first on Alpha Centauri and then on Earth sounds extraordinary, fascinating, and exciting, but what does science say about it?

The beginning and the end
It is interesting how the event that puts an end to living beings on a planet is also the one that can cause it in another place.
