Please explain to me why Black is better here?

[Chessqueen]

I am NOT a good chess player, but there are Experts and Masters players here that can break down this position and explain to me why Black is better here After the White bishop took on c7?

Just a guess, but I suspect that the white knight is holding things together for white, but can be easily be driven off or captured.

The other thing of note is the open h-file, which looks like it could be better used to black's advantage rather than white's.

Looking at engine analysis, it looks like Black has a combination to win a pawn after e.g. ..Rd7, Bf4, Qa5 and here you have to notice Black's double threat of capturing the a2 pawn AND Qb6+ forking the White king and b2 pawn.

Looks to me like simply a matter of king safety.

White's king will never be fully secure and black can simply keep queens on and harrass him endlessly.

Ideas like kicking (or capturing) on e4, playing ...Ng5, ...Qg6 and maybe even ...Rd5!? come to mind.

White doesn't have a comparable plan because black's king is completely secure.

Black has more active pieces - particularly the rooks; and better king safety.

I tried four engines which all gave black an advantage. Rebel 16.3 gave a large advantage:

I was curious to see the role of relative king safety in this position so I tried a few changes to the position.

- change white pawn from b2 to b3. This doesn't affect the king side but black's advantage reduces significantly. Why? Because White no longer loses a pawn on the queenside

- add a white pawn to h2 and a black pawn at h6. This improves White's king safety and closes the h-file but Black's advantage increases

- the bishops of opposite colour is significant. We know this can affect attacking/defending. It so happens that White's kingside is weak on the dark squares but he is the one with the dark square bishop and Black doesn't have a dark square bishop. Again transfer White's bishop to a light square such as b3 (or d3) and Black's bishop to a dark square such as e7 and see how Black then has a clearly won position

Thanks you all for making it clear as water to me.
