Scientists are finally laying down the hypothesis that the zero signs of alien life forms in the universe may be due to the fact that their life spans are pretty short.
Astronomers have found many planets that resemble our own earth around various star systems. The fact that they may be inhabited by aliens has not escaped the vision of these experts who cannot help star-gazing.

Now that the number of habitable planets has gone up to hundreds of billions of potential life sanctuaries, why is it that we cannot find any life forms in the known universe? Why is earth the only repository for life in the cosmos?
The search for aliens has become a sort of central theme and pet obsession with astronomers and astrophysicists. All telescopes are pointed towards the heavens to catch even a brief glimpse of life forms.
Space missions to Mars also raise the hopes of scientists that there may be life forms there. Yet the hopes have been dashed to the ground. Are we being simplistic and gullible in our exploration for the sake of life forms in outer space?
Well, even now many researchers say that the greater the number of planets, the more are the chances of there being life on at least some of them.
However, the rocky planets face such extremes of temperature and pressure that any life forms that are extant will most likely be bacteria of the most primitive kind.
Also they will right now probably be in extinct fossilized form. So, like dinosaurs do not exist anymore, these bacteria are difficult to detect due to the fact that they are not alive anymore.
It seems that early extinction could be the mode of the universe and the burgeoning of life in such grandeur on earth is nothing less than an anomaly, according to DailyMail.
The reason given for this is that the primitive conditions for life are rather unstable to begin with. Just like you need money in order to make more money, planet need to be inhabited in the first place in order to be inhabitable by life.
Such is the paradox of life in the universe. So while life may have been present on all the planets once, it probably died out so soon that nothing solid exists of it today.

Even Mars, Venus and Earth were pretty close in chemical conditions and terrain during their early evolution. Yet today they are so far apart from each other that there is no comparison between them.
