Interplanetary Space Dust brings life to Earth?
Scientists are now saying life could have been seeded on Earth by living organisms travelling through space on strong flows of interplanetary space dust - and vice versa.
They have previously speculated that comets and asteroids could have brought the building blocks of life from distant planets.
So perhaps life never originated in a primordial soup on Earth? That feels sad. In that Earth never created its own life story. That we are not unique in the Universe. But just the descendants of aliens.
