So the earth is constantly being bombarded by space dust and meteors every single day. How much might you ask (or maybe you didn't ask ever or don't care, but I'm gonna tell you anyways).
The earth gets hit by three metric tons every day. So 300,000 kgs or 660,000 lbs. That is an insane amount of weight every single day. Well to you and me it is anyways. But lets consider that the earth weighs roughly 6,000,000,000,000,000,000,000,000 kgs or 13,000,000,000,000,000,000,000,000 lbs. Now 660,000 lbs is basically nothing compared to that.
Of course if we keep adding that up that's 110,000,000 kgs a year or 250,000,000 lbs. Which still doesn't even come close. It's about a 1/6 zillionth of its total weight. Still not that much. But lets keep going. If we say the earth is 4.5 billion years old then that really starts to add up. Close 495,000,000,000,000,000kgs or 1,125,000,000,000,000,000lbs. Now that is some substantial weight that can't be overlooked anymore.
