why I use “main” instead of “body” tag?
Welcome to the forums.
We would not use it instead of BODY, but as a child of the body.
body
header
main
footer

Isn’t “main” used outside of “body” in the given example sir?
In well formed markup, the <body></body> is the outermost content container. It’s sibling is the <head></head> element that contains all the metadata. <header></header>, <main></main>, and <footer></footer> are all children of the body, at the very least, though they could be children of <section></section> or <article></article>, which are also descendents of BODY.
If we look at the specifications we will find that HEAD and BODY are optional elements, though we don’t see this in practice for a full blown web page. Typically page fragments that are merged with the page via AJAX are stored as plain HTML, but the following is valid for simple documents…
<html>
<div>
<h1>heading<h1>
<p>textual content</p>
<p>textual content</p>
<p>textual content</p>
<p>textual content</p>
</div>
</html>
If our document uses <html></html> to wrap it, then it is HTML that it contains.

i thought html must contain and and it is not optional… but is it optional??
i didn’t know that.
isn’t it are optional rather than and ???
That they are, under stripped down circumstances. We can give a browser nothing but gibberish and it will still render it to its best ability.
Hello World
Is not HTML, but since it is text, a browser makes it HTML, and renders it. Browsers render text as HTML.
Where it fits in normal flow is another question.
