Can new chess openings be created?

I know names of allmost all opening but i have no idea what Tartakower attack could be

It Is a variation of the indian game named after the polish chess player Savelij Grigor'evic Tartakover or Xavier Tartakover in french

It Is basically d4 and g3

I adduced some changes to my original opening(the one who was supposed to be a variation of the Tartakower attack),this is one of the many variations that i came up with(i changed It multiple times creating like 12 variations of the opening)

can someone tell me if this opening as black already exists...

here i have it against the London system...

you may need to flip the board...

not any good ones. but new variations happen all the time.

If this photo is the cow, I been using this since I learned it in 2016 from a Grand Master in Colorado Springs. Only it's stopped short, like they tried to do the same opening but failed. To finish the opening move the Bishops to D2, and E2. Than Castle on the king side. No one created a new opening, they failed at finishing a opening
