Ask AI: Are we humans also part extraterrestrial?

Scientifically speaking, there's no established evidence to suggest that humans are part extraterrestrial. However, some theories propose interesting ideas. The panspermia theory, for instance, suggests that life on Earth might have originated from microorganisms or chemical precursors of life present in outer space, which were brought to Earth by space dust, meteoroids, asteroids, comets, or even spacecraft. This is speculative and not universally accepted in scientific circles. In terms of our physical substance, we are composed of elements that were synthesized in stars, so in a symbolic way, one might suggest that we're 'star stuff'. Regardless, our known biological evolution and genetic heritage is rooted firmly on Earth where the diverse life around us evolved over billions of years. Astronomy and physics provide us with a cosmic perspective of our place in the universe, but biology and anthropology teach us about our specific journey as a species on this planet.
