These two things alone, ignoring any other things "observed" as dark matter, says that there is something there. Something that causes these effects.
It's simply called 'dark matter' because we don't know what this 'stuff' is yet. But there is sufficient evidence to tell us that this 'stuff' is there.
I agree that astrophysicists claim that gravity has been observed to bend light in certain areas, wherefore they have concluded that as evidence of the 23% of reality being "dark matter". "Dark energy", however, as far as I know, has not been evidenced by any observations and that is supposedly 73% of reality.
Re dark matter evidence:That, and CMB anisotropies and structure formation.
Saying 73% of reality sounds a bit theatrical. "73% of the energy density" is more like it
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
