Question

I just wanted to know because alot of people are saying conflicting things

Answer 1

It is exiting to do something different. He, she or it can become exited when thinking of doing something very exciting.

Answer 2

Both are adjectives that express emotions.

I am so excited. 

It is so exciting.

Just memorize both of these and you'll soon understand the difference intuitively.

Answer 3

The basic rule is that -ed ending adjectives refer to people only whereas -ing ending adjectives can refer to both objects and people.

Thus we can say someone is excited or exciting but we can't say that something is excited, only exciting.

Answer 4

If you say I’m excited it means you experience the emotion of excitement. If you say I’m exciting it means others experience the emotion of excitement thanks to you.

It’s exciting - something brings the emotion or excitement to you. You could say about your cat “it’s excited, or it was excited, look, how excited it is!” but not about other objects that cannot breath - you need to have a breath in your lungs to be excited;)
