Hi everyone;
Can someone explain to me the difference between does/is; when questioning.. I am confused

for an example say " do you go there " and "are you going there"
Another example " Is the following sentence correct " and " Does the following sentence correct"
Another one " does it doing the same thing again " and is it doing the same thing again"
another one " are you work there" and " do you work there"
I am really confused about where to use IS and DOES ? Can someone please explain it to me in basic English (layman's ). I don't see any differences between them; both seem meaningful to me ? what is the best rule of thumb to use the correct questioning (DOES/DO vs IS/ARE) ?
Thanks heaps
