Friends ! Alien bugs may have been transported to Earth, scientists say. Alien invasion could explain how life got started on Earth Some organisms from Earth, like tardigrades, are known to be able to survive in space!!! Aliens might have been carried to Earth on space dust, according to new research. Bugs might have flown across the universe and onto our own planet, and bugs from our own planet might have made the same journey, flying off of Earth and onto other planets elsewhere in the galaxy.
