&gt;We believe that the Bible is both internally (theologically) and externally (scientifically and historically) consistent. 

&gt;The Hebrew Calendar covers roughly 6,000 years of human history and it is generally accurate (possible variation of around 200 years).

I've always wondered how craters on the moon fit into the Young Earth Creationist worldview.

Craters are formed by asteroid impacts.

There are lots of craters on the moon and other extraterrestrial bodies. So the moon, Mars, ect. must have been hit by lots of asteroids

If lots of asteroids hit the moon, then a lot must have hit the Earth. This is because the Earth has a larger surface area and gravity than the moon, Mars, or moons of Jupiter.

But there are few craters on the Earth compared to the moon. We know lots of asteroids must have hit Earth (Earth's gravity and surface area and the observations of other planets in space.). There must be some other reason for why the Earth has few craters than "no asteroids hit Earth."

The available reason why we don't see craters on Earth is erosion. But craters from asteroid impacts would take much longer than 6,000 years to erode. Just look at the pyramids compared to craters on the moon. The pyramids have been around for 3,000 years and are much, much smaller than many impact craters on the moon, which are hundreds of miles across.

So, if we assume asteroids must have hit the Earth (a very plausible assumption given the evidence), and assume that erosion/tetonic plate movement is the reason why we don't see the effects of this bombardment (No other known force, try thinking of a physical force that can erase craters hundreds of miles wide and see if there is evidence for it), then it is clear that the Earth is much, much older than 6,000 years, which is inconsistent with biblical theories with state this.

So, **A)** how did craters on the moon and Mars get on the moon and Mars?  And **B)**  Why does the Earth have so few craters compared to other bodies?
