Listening to BTS say 시작! So many times in their Run BTS variety show has made me really familiar with this term.

Already knew this one because of JOLLY.

Why can't I say start, cause it is casual?

[LilyDrimm]

Isn't "let's get started" right? That's how I would say it in English, rather than simply "let's start"...

[LoreGuKi]

isn't begin the same as start?

[yoongiibae]

I've heard 시작하겠습니다 (We'll get started) a lot too.

Do you actually need the "let's" for this?
I thought the "let's" in English was an example of an equivalent level of politeness in which the sentence is said ?
