The conventional current and the electrons are moving when we give the supply. Then how you know which is came first.
In a closed circuit, the conventional current flows postive to negative charge and the electrons moving negative to positve terminal. Then how you know which is first.

Above @Ksk had the exact explanation of electron-hole theory, hole flow direction is considered as conventional flow direction and protons are not holes, holes are the vacant spaces left due to the motion of electrons. So, conventional flow is exactly opposite to the flow of electrons.

Conventional current is due to the migration of holes (i.e flow of protons). Hole is nothing but proton, hole forms due to the lose of electron. Conventional current flows from +ve to -ve direction. It means holes reached first than electron to destination.

In the question, they mentioned the discovery of the current flow.
So the conventional flow of electrons was assumed by the scientist first and then they were proved wrong and then they realized that current actually flows in the electron flow pattern.

Hole is NOT proton. It is deficiency or absence of electron. So when any hole is moving from point A to any other point B it means an electron is moving from point B to point A. I mean it is wrong saying which current flows first or second.

Protons can't flow out of the atoms but in the conventional current flow in case of the semiconductors the holes (vacant spaces created by the electrons) which are assumed to be positive flow in the direction of the conventional current.

Conventional current flows in a direction opposite to that of electron flow.
Electron flows from negative to positive. Protons never flows.
In case of semiconductors holes flows in the same direction of conventional current flow.
Electron flows from negative to positive. Protons never flows.
In case of semiconductors holes flows in the same direction of conventional current flow.

Mass is inversely proportional to the speed. Mass of a proton is 1836 times of an electron mass. So the speed of electron > speed of proton. Electron current come first than conventional current (i.e Current for proton).

Conventional current is due to the migration of holes (i. E flow of protons). Hole is nothing but proton, hole forms due to the lose of electron. And this current flows in opposite direction to the electron current.

To find the conventional current flow, first you must go to electric current defination in one word " the flow of electrons or charge" is called an electric current.
That's why conventional current flow first.
