Extraterrestrials

Extraterrestrials are hypothetical life forms originating from outside the planet Earth. The term encompasses a vast range of potential beings, from simple microbial life to highly intelligent, technologically advanced civilizations. Belief in extraterrestrials is driven by the sheer vastness of the universe and the possibility of life arising elsewhere given the right conditions. Research efforts include the search for radio signals (SETI) and probes to other planets. Whether they exist and have visited Earth are topics of ongoing scientific debate and speculation.
