How to create a PDF Fillable Form

Hello
You may get this question over and over and yes, I did a search but cannot find what I want/need to do.
So, what is the best way to create a fillable form using Acrobat?
Or?
Should I use another program like Illustrator, InDesign?
What is the best way?
How do you do that?

Here is my problem now.
I received a pdf form file that was edit in god knows where, because yes, is a PDF but is kind of mess up.
For example, most text boxes are not aligned so if I want to edit anything, the boxes overlap each other
and is almost impossible to select anything without moving something that I don't want to move.
Do you know what I mean?
So, I thought that the best, fastest and better way is to recreate the whole Enchilada.

I had very little experience with Acrobat, I used it almost every day but just to sent files, not to modify them
INSIDE the program.  However, I can make my way around.

I have the latest Acrobat installed (I'm a paid subscriber to the Adobe stuff) so that what I have.

Any help will be appreciated A LOT!

Thank you
