Francis Crick had a similar theory, he published in a book I read recently, “Life Itself, Its Nature and Origins”, that theorizes that life on Earth could have been started by an advanced race of aliens who sent a spaceship here full of ‘spores’ long ago to seed the planet with life.
I think the even more simple explanation that neither author proposed is that the blueprint for life got here naturally, from a comet or meteorite carrying frozen RNA and DNA in viruses, which are not technically ‘alive’ but can nonetheless perform genetic surgery and join two single helix strands of RNA together to make a double helix of DNA, with all the instructions to make proteins that could develop into something we call ‘life’, a simple cell that could reproduce and be the last common ancestor of all of us.
Even more complex life could also survive inter stellar travel frozen on ice, extremophiles, like Waterbears, Tardigrades, the oldest and toughest animal on the planet, 5 time world champion apocalypse survivor. Scientists figure they must have come from another planet because they can survive 6x’s the greatest pressure on Earth at the bottom of the deepest ocean. There would be no other way to develop that ability unless they evolved on a planet with much greater pressure than Earth’s.
They can also survive 10,000 X’d the amount of radiation it takes to kill a human and they have survived in the vacuum of space.
