If an alien civilization were watching Earth, they would detect an elevated level of methane in our atmosphere. Methane eventually combines with oxygen and should disappear, so this means something is producing it. Bovines produce a large amount of methane in their intestines. Therefore bullsh*t is proof of life on Earth.
