[AC Question]

I mistakenly removed Home Button in my Moto G2 and not able to retrieve it. It was the button which comes at the bottom of main screen having a parallel pair of 3 small dots.

Welcome to Android Central! That's the App Drawer button, not the Home button. You normally can't get rid of that, unless you're running an alternative launcher--are you?

Also, let's make sure you're talking about an LG G2, and not a completely different Motorola phone. If you're talking about the 2 rows of 3 dots inside a circle, that's the app drawer button. I don't see that there's a way to delete it, but it can be moved to your home screen. Is it possible that's what you did? If so, you can just long press and drag it back to where you want it.
