which opening is easy for beginners to learn?

I'm a second vote for the Italian, for the reasons already stated. You can throw in the occasional Evan's Gambit on move 4, which can be a lot of fun, as well.

1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5
1. e4 helps put a pawn in the center
2. Nf3 knights before bishops and develop your pieces
3. Bc4 develop your pieces
Other openings might be okay but this is the most basic as needed for beginners

Sicilian Najdorf is my go. I dont know if it will be helpful to beginners though
Hardly the easiest for either color... And I realize you didn't imply that tbey are easy, with so many lines and sidelines. It is impossible to memorize all but indeed very exciting to play and for me taking years to gain experience in its diverse positions. My favorite to play as well btw.

d4 openings tend to be easier to play as they tend to be quieter and less sharp until middlegame begins. You will through experience and hopefully study... Learn which lines / Style of play including your regular opponents style... Best suit you.
However, openings that will help teach you specific chess ideas that you might benefit from are Ruy Lopez, Italian, Vienna, Evans Gambit, and Queens Gambit as white, while Ruy Lopez, Italian, Caro Kann, and Queens Gambit Declined may be useful as black for a beginner. Yes, learning both sides of the Ruy Lopez and Italian is useful to you since you may end up playing those more often and the best way to know an opening is to understand the ideas and objectives of both sides to it. They are also great openings for beginners because they follow opening principles closely unlike some openings that require more thought and exceptions to otherwise natural opening principles ideas.
Have fun with chess and your great chess adventure!

French is so OP. Most people don't play against it so you will have an advantage if you prepare for it and I can give you a mini lesson for anyone who wants to play French
If you want to learn more about the lines, I highly recommend you check my study here. It covers the Advance, Exchange, King's Indian, and the Tarrasch which should cover what beginners will face

At your level, stick with opening principles. Openings do not decide your games.
I hear this response all the time. Does it answer the question? Was the question which opening will decide my games?
How does one "stick with opening principles"? Which principles are the most important? Which one's have exceptions?
If both players played using opening principles, wouldn't there be a "most principled opening" that would be the easiest to learn and understand?
Would 1.e4 e5 be a start? And then what is the most principled move for White?

Giuoco Piano. Rapid development/castling. And after move 3, there's plenty of solid lines so it's hard to go wrong. And if you're playing against other beginners, there's always the chance for fried liver.

I disagree with the advice to not learn openings as a beginner.
If they were good at "principles" they wouldn't be a beginner.
Rather, I recommend learning only a few openings, and only the initial lines. If you're going to make a ton of mistakes, you might as well start off with a decent position.

Once you become a titled player you can start memorizing openings.

When you get really good they start calling you things: Expert, Master, Senior Master, FIDE Master, International Master, Grandmaster.

The point of learning the Opening principles is that they will guide you in most positions you face in the opening and help you avoid bad opening moves regardless if you know the opening being played or not. Learning 10 moves of Opening theory is rarely going to be as helpful as learning opening principles because the Opening theory only gives you guidance on that one opening and any deviation (which happens in most games) from the known theory leaves the beginner with no idea what to do from there- even if they are presently sitting in a good/great position. We see this happen all the time in beginner games.
The other reason to avoid Opening theory for beginners is they tend to begin placing far to much emphasis on learning Opening theory and worse begin to hop from one opening to another, wasting hours of time in the process, trying to find the opening(s) that "are right for them". Here's the deal- beginners have no idea what openings will be right for them because they have little experience with chess in general and could easily find out they like or are good at certain structures later in their chess journey than they initially thought.
Opening principles help beginners understand the right objectives and process of developing and are a far better guide when they arrive into new positions they have not faced before. It's the fundamental basis for learning all Opening theory, unless you plan to just memorize reams of various lines, you have to understand the point of moves and why you're making them, which is what Opening principles help explain in a general way.
There is a general hierarchy of chess knowledge that players should follow for a proper and systematic learning process and Opening theory is not the priority initially. It's learning fundamental aspects of the game, basic endgames, opening principles, basic tactical themes and learning a coherent thought process to evaluate positions and determine candidate moves and ultimately your next move. If you're spending hours of learning Opening theory when you still systematically hang pieces or miss hanging pieces and basic 1-2 move combinations, you're spending your time on the wrong areas in chess and you'll see minimal progress.
There's a reason why something is harped on all the time to beginners- because it's a universal truth known to any experienced player out there.

Does all of this mean there are no openings based on and supported by opening principles?
Sorry sorry white pawn to G3 not F3
