There has been a plethora of articles and significant dollars dedicated to the search for extraterrestrial life, particularly intelligent life. In recent times several […]

The Habitability Habit: Exaggerating Earth-Likeness

Secularists put too much hope on some aspects of Earth-like exoplanets, but sometimes reality keeps their imaginations in check.

Hope, Not Evidence, Drives Astrobiology

Earth-size exoplanets are not evidence for alien life. They are evidence for orbiting bodies.

Faint Young Sun Paradox Solved?

A major mystery for materialistic planetary science is solved—if you can swallow the miracles required.

Only Earth Is a Life Haven

Here are more discoveries that make it reasonable to think complex life is rare in the universe, and might be unique to Earth.

More Challenges to Astrobiology

There aren't likely as many places to live outside of Earth as earlier hoped.

New Thoughts on Habitable Planets

Astrobiologists are trying to standardize the requirements for habitable planets. Do they get them all?

Do You Know How Lucky You Are to Live on Earth?

The factors that make life possible came together so beautifully, even materialists have trouble knowing why we're here.
