Earth vs. Snowflake

Get out your abacus sliderule, calculator and your best guesstamation skills: Which is greater…the number of grains of sand(earth, dirt, etc.) in the world, or the number of snowflakes that have fallen since the begining of time? thanks for the help.

Preemptive strike of 11/18/07:
Here’s a big number for you: How many snowflakes have fallen on the earth?

Would the number of snowflakes fallen be only limited to our planet?

He said “since the beginning of time”, so he’s not limiting the time to the age of the earth, anyway. Hah, he blundered!
