Dream on.
In the last World Chess Championship (Carlsen-Caruana, 2018) there were 12 regular games. Here is how each started.
1. e4 c5
1. d4 Nf6
1. e4 c5
1. c4 e5
1. e4 c5
1. e4 e5
1. d4 Nf6
1. e4 c5
1. c4 e5
1. e4 c5
1. e4 e5
1. e4 c5
So white played e4 in 8 out of 12 games, and c4 and d4 just twice each. Could there be a reason for that?
In 2016 it was Carlsen-Karjakin and it was a similar story. White opened e4 in 9 out of 12 games with d4 being played just 3 times.
In 2014 it was Carlsen-Anand. Guess what? e4 was still the most popular. But this time being played 6 times out of 11 games (with d4 being played 5 times).
In fact, Carlsen has opened e4 in 701 of his 1506 games. He particularly likes it when his opponents play the Berlin Defence to his e4. This has happened 39 times and Carlsen has won 24 of these games and lost only 6.
On this large database of games, https://www.chessgames.com/perl/explorer, e4 is the most popular opening for white. On chess.com's database of master games guess what the most popular move is? You guessed it, e4.
Don't you think that clever people like Anand might have thought about whether the Berlin Defence could be the answer to e4?
Nf6 on move 2 (as shown below) has a poor record on the chess.com database (white wins 37%, draws 47%, black wins 16%).
Nf6 as a reply to Ruy Lopez (as shown below) does not fare much better (white wins 33%, draws 45%, black wins 22%).
There's no evidence to back up what you are saying.
e4 is best by test.
Let's imagine ourselves in a very hypothetical world, that is very possible. Most Grandmasters believe e4 is the best, hence the databases. But what if everyone played the Berlin defense or Petroff? In the Berlin defense Nf6 puts pressure on e4 and the best move is to castle to develop the rook. But you lose the e4 pawn, and then the game gets to a very near ending. Black gets a more active position, with the bishop pair advantage and an active king. So maybe instead of going into a nearly ended game, d4 gives more chances for a win with play on the queenside.
