Why does everyone start with this?

the pawn in front of the king is moved one or two spaces so the queen can come out almost immediately. I cover it with my knight. I have a set up I call "kings castle" that I am able to finish by the time they actually start legitimately attacking.

Diagram or notation needed.

You say the pawn in front of the king 1 or 2, likely 2.  Nobody plays 1.e3.  1.e4 is something you will face a lot.  As a clear beginner, you should claim central territory with 1...e5.

"... For players with very limited experience, I recommend using openings in which the play can be clarified at an early stage, often with a degree of simplification. To accomplish this safely will take a little study, because you will have to get used to playing wiith open lines for both sides' pieces, but you can't eliminate risk entirely in the opening anyway. ... teachers all over the world suggest that inexperienced players begin with 1 e4. ... You will undoubtedly see the reply 1 ... e5 most often when playing at or near a beginner's level, ... After 2 Nf3, 2 ... Nc6 will occur in the bulk of your games. ... I recommend taking up the classical and instructive move 3 Bc4 at an early stage. Then, against 3 ... Bc5, it's thematic to try to establish the ideal centre by 4 c3 and 5 d4; after that, things can get complicated enough that you need to take a look at some theory and learn the basics; … As Black, I think that [players with very limited experience] would do well … playing 1...e5 versus 1 e4 …" - IM John Watson in a section of his 2010 book, Mastering the Chess Openings, Volume 4

Perhaps it would be a good idea to look at Discovering Chess Openings (a book about opening principles)

"'Black proclaims by his symmetrical reply 1...e5 his firm decision to cross swords as quickly as possible with his adversary and (in spite of 'the move') to meet him on an equal footing in the centre of the board, whereas a passive reply such as King's or Queen's Fianchetto (1...g6 or 1...b6) would allow White to occupy the centre immediately and for good by 2 d4.'
'After the typical moves 1 e4 e5 we frequently see a lively struggle, seeking in particular to gain the mastery in the centre.'
'Each move in the initial stage must be telling, in other words, it must contain some threat of an immediate nature (attack on a pawn, an effective pin of a piece, unpinning, counter-attack, etc.), and a game of chess of this type resembles an encounter between two fencers where thrust and parry follow and offset each other.'
Savielly Tartakower (A Breviary of Chesss)
1...e5 is arguably the simplest and most logical reply to 1 e4, taking space in the centre and opening diagonals for the queen and bishop. It has been played by every world champion in the history of the game, and many of them played nothing else. ..." - GM Nigel Davies (2005)

I think you're talking about the so-called Scholar's Mate:

You're right, it's a naive attack, easily defended.

Apologies. I wrote this thread on my phone and didn't know about inserting boards. Here is the opener I am speaking of for example. 

I always always ALWAYS use my knight to block the possibility of the queen popping out too early in the game. Here is how one of my quickest games with an opener like this went. I played black. Since so many people open this way, I almost prefer to start black. 

And yes, I know that I could have Mated earlier on than what I did, but I'm still getting back into chess in the first place.

It's hard to follow your logic. 1.e4 is not generally played to get the queen out early, but to stake a claim in the centre and open a line for the bishop. Moving the queen early is not usually a good idea in the opening, so there's no need to do anything to prevent it - just drive the queen away when it makes its premature move. The two openings you show are very different, and White doesn't move the queen at all in the second one, nor do you make any knight move that could have prevented it.

Yes, I have seen this a few times over my time of playing since I posted this. However, more than once, the person I'm playing has attempted to bring the queen out in 4 moves. I'm just questioning why most of the people I've played are opening with the pawn on either side of the queen.

I'm just saying that it's a predictable and boring opener. But I suppose that it's a good one. 

I use variations of this opener and Will sometimes sacrifice pieces just to make it a quick game and members  like ghost of push get so mad. I dont think he knows what boneheaded is. To each his own. Ghost of push dont bully. Your on of those guys 

Its members like this who have no patients for getting beat in 4 moves and get upset is only when i do it. Dont cry i wont use this opener. Oh, here is a thought, Defend it. 

I also do this. Although I am a lower rank thank probably most, I certainly have experience IRL and in game of having to sacrifice pieces. I've mated more often with a queen or rook simply because I sacrificed a knight or bishop to get closer to the king or force a piece to move the way I want them to. It's an interesting opener for sure, and I for one can say that I enjoy playing chess regardless of who is playing and how they open. I was just hoping to find some clarity over the reasoning. 

Yes, it's even an excellent one, arguably the best, so people  will naturally play it.

Is it predictable? Yes, because people want to play a strong move and they want to play an opening they are comfortable with. 1.e4 is just easier to handle than the other options, mainly because the game tends to open up quickly (meaning that center pawns are eliminated, so there are open lines and diagonals), which leads to a stable situation enforcing active piece play. That doesn't create as many planning problem as other openings - often you will have a tactical clash early in the middlegame. On non-master level, the vast majority of the games will be decided tactically, so tactics is the most important thing to practice anyway.

So it's one of the best moves, it's easier to play for beginners and they often get a tactical fight. Practically all teachers will suggest this move to their students.

Re boring: the game will get interesting soon enough.

Very well said

I agree! Very well said my friend.

I played this game recently in an attempt to see why the move is so popular. 

As I understand it, 1...Nf6 is considered to be an acceptable reaction to 1 e4, but, if you keep on using it, you will sooner or later encounter 2 e5. The resulting sort of game may not be to your taste. There are other ways to deal with the "queen popping" problem. GM Emms seems to have been fond of presenting this (perhaps composed) game:

As you progress to higher ratings, I imagine that you will not see "queen popping" so often. In the meantime, you may want to do some reading from two books by GM Emms.
