NASA scientists claim to have found key elements that state that primitive aliens could be living on Titan, one of Saturn's biggest moons.

It is as per the various chemical compositions found on Titan's surface the scientists at US space agency NASA have concluded that forms of life may be viable and very much present in the planet's atmosphere.

The finding relies upon the analysis of data sent from NASA's Cassini probe that has been detailed in two separate studies. The first analysis in the journal Icarus, shows that hydrogen gas flowing throughout the planet's atmosphere disappeared at the surface. This suggested alien forms could breathe.

On the other hand the second paper in the Journal of Geophysical Research highlights that there was lack of a particular chemical which supposedly had been consumed by the living aliens, The Telegraph reports.

Chris McKay of NASA, stated: "We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan, similar to the way we consume oxygen on Earth."
