Is Earth's Atmosphere an Import?
garg0yle writes "One of the questions about the formation of our planet is: where did the atmosphere come from? One theory is that the oxygen, nitrogen, and other gases were part of the coalescing ball, and 'seeped out' during the final stages of the planet's formation. However, a new article at Wired says isotopic analysis of krypton and xenon indicates that they (and the rest of our atmosphere) may be of extraterrestrial origin, either arriving via comets or being swept up from gas clouds."
I'm an atmosphere skeptic.
The existence of the atmosphere is a liberal hoax perpetrated on us by the scientific community.
Can you see it? No. What are they trying to hide?
You forgot to capitalize an instance of "water" in your first and last sentences. I also think you should capitalize "moons", "worldly", and "substances", for good measure.
God created the earth?
Honestly who cares?
Atmospheric scientists?

... indicates that they (and the rest of our atmosphere) may be of extraterrestrial origin..
Duh. Why do you suppose they call it "krypton," Kal-El?
Wow, 'expoplanet'. Dunno how I typed that.
It's like the sales-convention planet.
It will be the first to be nuked out of existence from orbit.
Gravity is a lie perpetrated to keep the people down!
You have the right to remain sentient. If you give up the right to remain sentient, you will be elected to public office
Just a theory. Why should we believe it more than Intelligent Falling?
