Has there ever been a sign of extraterrestrial life?

Answer

Dear Benjamin

Humans have been bringing Earth life into the solar system for 50 years, so actually the answer is yes. There is now life beyond Earth. For example, inside our satellites.

A microfossil has also been found in the Martian meteorite ALH84001, which crashed into Antarctica in 1984. The microfossil is the size of Earth’s smallest bacteria (200 nanometers). Some scientists believe this is evidence of early life on Mars.

Certain gases have also been observed on Mars, which may have originated from underground life. However, only a minority of scientists are sure that this points to extraterrestrial life.
