Avoiding debates & looking into Planes/realms What should I do if a lot of my friends and family are trying to prove Buddhism wrong with the laws of impermanence or planes of existence, &amp; I do not want to debate this with them as I do not want to arise the Poisons, but I keep getting into it?

Also, on the topic of planes of existence, is there any proof in a sense to their existence, or at least anything verifiable by experience to understand them better?

I believe the planes, I just was curious about that.

Metta to all!
The planes of existence can known as psychological states of mind therefore it is easy to prove them to others. People have hellish suffering; people behave like animals; people can be ungrounded rootless ghosts &amp; addicts; people can live a godly life of wealth, power, luxury or bliss; people can be humane. 

Planes of existence are depicted below. An explanation is: The Wheel of Life by Barbara O'Brien.
