Giant stars are quite short-lived, with Betelgeuse estimated to have at most a 15 million (not billion!) year life before becoming a red supergiant . If simple life did evolve in time, it was wiped out about 100,000 years ago as Betelgeuse became a supergiant. One last fun fact: Betelgeuse is about 125,000 times brighter than the Sun in absolute luminosity.
