   Is there scientific evidence for aliens?

   • The sobering reality is that there isn't any yet. There's no scientific evidence for aliens in the declassified UFO videos, in mutilated cows whose injuries are blamed on extraterrestrial activities or in purported alien bodies. Nor is there any such evidence in the formal academic research. Live Science checked in with experts to make sure.

   Could A Level 7 detection be a proof of alien life?

   • Further observations would need to rule out nonbiological ideas before, finally, follow-up observations showed other examples of biological activity in the same environment, making a detection a level 7—essentially, proof of alien life. Part of the hope is that the scientific community at large would agree to use such a scale.
