Hopefully this will finally trigger the long anticipated alien invasion.
A lot of scientists think we are the aliens. Earth was terraformed and we are a product of interstellar "seeding" OR gene splicing OR both
Not likely. Not as an individual species. We have too much genetic kinship to every organism on earth to have been "planted" from abroad. We obviously evolved from other creatures on earth.
Though if you're suggesting that the entire biosphere of earth is the result of alien astronauts leaving a candy wrapper on the earth's surface four billion years ago then...that
could be. The alien bacteria on the candy wrapper might have colonized earth, spread, diversified, and evolved, spawned eukaryotic cells three billion years later, then multicellular organisms three and half billion years later and so on.
