When you take into account the size of the universe, the odds of extraterrestrial life existing somewhere in that vast space are more than good. Scientists claim that we will have inconclusive proof of aliens living on other planets no later than 2040 which isn’t so far from now. They has also tried to determine how aliens will look and found proof and theories as to why they will not resemble humans at all. We’ve gathered the top ten reasons why aliens will look super weird and nothing like the human race in the list below.

Stronger Gravity

The best way to explain how gravity effects organisms would be if we imagine a hypothetical situation where Earth’s gravity is doubled. The chances of humans actually walking on just two legs would be miniscule as we would have to have shorter legs and larger bones because of a stronger force of gravity. Also, life in general would be smaller and shorter. The exact opposite would happen if we would imagine an Earth with half the gravity.

Different Atmosphere

Just like gravity, the atmosphere has a significant influence on how the life on a planet looks. Millions of years ago, Earth had a denser atmosphere than now, which resulted in creatures being able to grow larger; for instance the dinosaurs. This is due to the higher concentrations of oxygen they required, which was present in the thicker atmosphere. However, scientists have also managed to find specimens on Earth that don’t require any oxygen for living which means life without it is possible too. And that would certainly look completely different as well.
