Question from Moses:
I’m not going to enlighten you on my personal beliefs, because it is moot to my question that I will pose momentarily.

I have made note that your readers all seem to agree that science and rational thinking should be revered above all else.

And further understanding that choice is a free will, individual thought process or belief that may or may not be brought into actions.

So here is my rational, scientifically proven, free willed, intellectual question: “If there is no creation theory, then why isn’t the earth filled with abundant quantities of deuterium just as the rest of the solar system is?”

p.s. The world’s space agencies has sent, and continues to spend billions of dollars for, probes and robots searching for life, but science has proven that the water here on earth is certainly different than elsewhere in our solar system.

I await your response in earnest.

Answer by SmartLX:
Thanks in advance Moses, it’s almost never this simple.

Deuterium IS abundant on Earth; one in about 6,400 hydrogen atoms in ocean water is a deuterium isotope (which is just a hydrogen atom with a neutron) instead of the usual type. This ratio is higher than some of the objects in space we’ve been able to analyse, and lower than others. All measurements within the solar system including on Earth have been within 1-2 orders of magnitude (specifically a factor of ~30), with Halley’s Comet and Comet Hale Bopp near the high end and Jupiter’s atmosphere near the low end. The fact that our ratio is closer to the comets has caused some to theorise that comet collisions with the early Earth are the source of much of our water. There’s nothing special or unique about the ratio at all.

Your personal beliefs may be moot, but to an extent they are also obvious. Only a creationist would make an argument from ignorance based on the supposedly unknown reasons for a scientific factoid (and I’m not surprised that the factoid itself is bogus, though perhaps you are surprised), or use the term “creation theory”. Only devout theists are creationists because faith in a creator is ultimately the only compelling reason to be one. You might be a Christian creationist or a Muslim creationist; few other religions have so many.

As for the water, we’ve known about the ice crust on Europa since the 1970s and it’s likely that Mars and Venus had liquid water in the past. Multiple extrasolar planets are the right distance from their stars to have liquid water, provided water exists there; here’s a list.
