That vs It. Which one will win?

[Paulys]

Hello reader,
My biggest problem what I can't distinguish where is difference between "THAT" and "IT".

I see that sometimes people use "IT" instead of "THAT".

So... When can I use That instead of "IT"?
By the way, I didn't find information about That & It through the internet.
If I Made any mistakes please correct them

You will need to post some example sentences so that we can see where your confusion lies.

Do you mean, for instance, why do we say "It's raining" not "That's raining"?

Please give some examples.

I have corrected your original post. Please note that there was no need to put your final sentence in a huge font and in red.
