What do scientists say about existence?

[Mr.Obvious]

Okay, Mr.Obvious, you are of the Pauca sapienti school of writing. In which case, you can do that school even better, no need to join internet forums to write out your thoughts, just look up people and talk with each other with your eyes only, and make grunts instead of speaking words.

I like to invite you and me to exchange thoughts on what is existence, is that all right with you?

You want to tell me that for you Existance is, that is enough for you to know what is existence.

Well, it is one thing for you to think that you know what is  something, but it is another thing to know how to tell others what you know of something, in words.

Pray tell me, how else can you tell people who use language, i.e. words, what you know of the something by which you have a word for and they have the same word for, but you care to put what you both know, with words other than the word itself, like in the present context, what is existence.

You care to put into words what you both know of the something, in the present context, existence, so that you both, or you and I we both concur exactly in concise, clear, simple language i.e. words, but not including that word of present concern, existence, what is existence

We will do it this way, here below; unless you want us to do it in another better way, then I will cooperate with you totally.

Here, I will ask you this question:
How did you come to know of existence?

Hrm. Hmmm. Mhm. Ugh.
