Question

Why do we write?(in-depth answers please)?

Answer 1

I do it when I want for whatever reason I want.

Answer 2

Umm...to memorialize our thoughts, traditions, opinions etc?  I really don't know a more in-depth answer. Sorry.

Answer 3

To communicate with people far away before we had phones. To make people remember. Just look at hieroglyphics and think about why the egyptians first wrote to understand why.

Answer 4

This sounds suspiciously like a question you're supposed to be answering for a writing class.  

Answer 5

To preserve, exchange and distribute information.  That's in-depth.

Answer 6

Because we can't memorize vast amounts of information.
