Don't Live each day like it's your last. Live each day like you have 541 days after that one where every choice you make will have lasting implications to you and the world around you. ~ Tim Minchin

Not strictly speaking true that the moon has no atmosphere. It does have a very tenuous atmosphere - and water!

"For most practical purposes, the Moon is considered to be surrounded by vacuum. The elevated presence of atomic and molecular particles in its vicinity (compared to interplanetary medium), referred to as 'lunar atmosphere' for scientific objectives, is negligible in comparison with the gaseous envelopes surrounding Earth and most planets of the Solar system—less than one hundred trillionth (10−14) of Earth's atmospheric density at sea level. Otherwise, the Moon is considered not to have an atmosphere because it cannot absorb measurable quantities of radiation, does not appear layered or self-circulating, and requires constant replenishment due to the high rate at which its atmosphere is lost to space."

It does not have a True Atmosphere™. Big Grin

Skepticism is not a position; it is an approach to claims.
Science is not a subject, but a method.

Insufferable know-it-all.Einstein God has a plan for us. Please stop screwing it up with your prayers.

Beginning an hour and half after closest approach, the Solar Wind Around Pluto (SWAP) instrument observed a cavity in the solar wind -- the outflow of electrically charged particles from the Sun -- between 48,000 miles (77,000 km) and 68,000 miles (109,000 km) downstream of Pluto. SWAP data revealed this cavity to be populated with nitrogen ions forming a “plasma tail” of undetermined structure and length extending behind the planet.

If Pluto is billions of years old shouldn't its atmosphere have all been lost a long time ago? The fact that it still has an atmosphere supports the belief that is was created only a few thousand years ago.

So ... it must be God, huh?

How can anyone become an atheist when we are all born with no beliefs in the first place? I am an atheist because it is the natural state of being we are all born into.
