New evidence from astrobiology “overwhelmingly” supports the view that life was seeded from outside Earth, a scientist has claimed.
Prof Chandra Wickramasinghe of Cardiff University says the first microbes were deposited on Earth 3,800m years ago.
The astrobiologist has helped developed the panspermia theory which suggests an extra-terrestrial origin for life.
He argues for a cycle of life as microbes find their way into comets and “multiply and seed other planets”.
In the article, published in the International Journal of Astrobiology, Monday, he argues humans and indeed all life on Earth is of alien origin, brought onto the planet by comets hitting the planet.
