Why Would You Rebase?

In real life, you might be working on a feature and it could last like a, you know, a week or two. If i just did the merge and nothing else in the order that i just described it, then the commit history would read, let's say on monday i'm checked out and allan was the last one to have merged in. I get it, but i younow, i'm living in the rill, right? And, and so,you know, i took the red pill. O wat was the blue pill? No, i m at any rate.
