NASA’s chief thinks we’ll find proof of alien life within a decade

Although interest in alien life has been present throughout human history in some form, it wasn’t until man actually developed space travel that people became truly interested in the subject, so much so that it has ingrained itself in our culture. However, decades of space exploration have yielded little in the way of evidence of alien life, but NASA believes that we could have definitive evidence of alien life within the next 20-30 years.
