The Earth does lose mass over time, but it gains a lot more than it loses. Losses are primarily due to lighter elements such as hydrogen in the outer atmosphere that have sufficient energy to escape Earth's gravitational pull. The Earth is constantly bombarded with cosmic dust, which accounts for a mass gain of about 30,000 tons per year. Most of this dust is vaporized as it passes through Earth's atmosphere and is uniformly distributed over the Earth. Assuming a constant influx of cosmic dust, mass gain over Earth's history is only 1 part in 44 million, a pretty small number. That would correspond to less than a meter of accumulation if the Earth had no atmosphere and no plate tectonics.

actually, its the other way around. the earth gains mass over time. a law in science: "matter(which makes up the mass of the earth) can neither be destroyed nor created. it can only be converted into other forms" How does it gain mass? Dust and other matter from space enter the earth.

Well let's see...so the earth is 4.6 billion years old at least that's what the Theory of Evolution and it's believers...so let's do the math.
30,000 Tons * 4,600,000,000 = 138000000000000 Tons
138000000000000 Tons * 2000 = 2.76e+17 pounds
This doesn't even account for how much the earth weighed at it's first appearance!
Something doesn't seem right here!!!!

everytime a being excretes methane the planet gains that much more density. but as it gains it pushes out some more. gotta make space to take space. Just wait to see how much mass earth will lose 2012.....

Due to meteorites I would think the earth gains mass.

yes, but it also produce mass overtime. It is affected in human activities and natural events.
