I can't find any diamonds on a server.

maybe you are not looking hard enough

Diamonds are rare. That is probably why you have a hard time finding them. I ran the calculations and my results indicate that you would have better luck getting a dirt block than diamonds.

But I am so brilliant and that is why it is easy for me to make fun of you. If you were smarter or I was less amazing by a hair, then you would probably understand. But you're not and I couldn't be, so incomprehensibility is your father.
