Hydrogen was the only element that existed after the Big Bang.
It coalesced former into clouds which got denser and denser.
The denser those clouds got the more their gravity increased until they became so large they formed spheres.
Those spheres of dense hydrogen kept gravitationally pulling in even more hydrogen and kept growing bigger and bigger and denser and denser so gravitational strength began to crush the core.
So much so that the pressure in the core caused heat, lots of it, and that tremendous heat and pressure then resulted in two hydrogen atoms fusing into helium.
Fusion. Meaning a nuclear reaction had commenced and the lord said let their be light (and heat) as the first proto stars were born in the universe, undoubted lots of them.
On burning all their hydrogen and with no nuclear reaction pushing outwards massively to counteract gravity, because that is all a star is - a constant battle between gravity pushing in and a nuclear reaction pushing out - those early stars imploded as super nova.
During the super nova explosions other elements were created,carbon for one and even water, and these got exploded outwards into clouds of stardust to form new clouds which themselves coalesced and formed more complex different types of stars( blue giants, red giants and dwarves andstars like our sun.
Which all, depending on their chemical make up, produced even more elements which were exploded out when they too went supernova.
The good news with carbon iron and other heavy elements in the mix planets started to form.
And 4.5 billion years later, 13.5 after the Big Bang, here we are.

Good point. Luton is even worse..,

Since 4 dimensional spacetime doesn't come into being until after the big bang there is no "before".
