Why Aliens will look like Earthlings

Why will ALIENS almost surely look like EARTHLINGS?

Two words, CONVERGENT EVOLUTION – in this case it works for two planets!

For life to start there must be a planet in the Goldilocks zone. That includes a temperature range that allows for liquid water.

But it must also have a certain atmosphere.
When the planet is too big, like Jupiter, it has the wrong atmosphere. When the planet is too small, like our Moon, it doesn’t hold in an atmosphere. Wrong atmosphere, wrong chemistry – no life.

That means that life planets always have THE SAME GRAVITY!

That means that the life on those watery planets with the same gravity will have life that faces the same natural selection as our planet.

That means that life anywhere will evolve to the best ways to: SWIM, WALK, FLY, and BURROW!

Convergent evolution means they will come up with virtually the same solutions to how to best swim, walk, fly, and burrow, that life did on Earth.

SO, if aliens are ever found, they should be much the same as life on Earth – CONVERGENT EVOLUTION!
