Planetary Habitability and Water

Habitability out there, thataway, was a simple concept: A planet had to be the right distance from a suitable star. There also had to be some water. Secular cosmologists and astrobiologists (yet there are no aliens to study) depend on atoms-to-alien evolution to happen.

Aside from the silliness of believing in abiogenesis despite science and reason, these folks also have to deal with how the habitability zone becomes increasingly complex. It gets more complicated the way water is vital for habitability in more ways than scientists previously considered.

There are books and movies about desert worlds where water is a precious commodity. Computer simulations greatly increase the suspension of disbelief in audiences because a world without water could not evolve  — a substantial amount of water, at that. Also, the water would have to be at a minimum level. Such information should inspire people to be thankful to the Creator for the world that he has given us, a world based in reality instead of imagination.

Imagining life on other planets was too easy back in Carl Sagan’s day. Put a planet into an orbit with a continuous temperature between 0 and 100 degrees Celsius, just add water, and presto! Evolution would take care of everything. Since then, the list of factors required to support life on a planet or moon has grown. In his book Spacecraft Earth, contributing author Dr Henry Richter listed 15 requirements for a planet to host life (p. 29). Multiplied together, the probabilities of meeting those needs would make life uncommon in the universe. Now we can add another requirement.
