the only thing absolute is the speed of light?

You must distinguish between relative and relational. These are two
different terms.
What you think you mean by "everything is relative" actually means
"everything is relational". Relativity does not imply lack of
absolutes.
Actually, Minkowski, I think it was, proposed to Einstein to rename
the theory of Relativity to Theory of Absolutes but Eisntein said it
was too late but he agreed about the correct name.
For example, acceleration is absolute. If you have two observers and
one is accelerating towards the other, you can perform simple local
tests in their frame of references to decide which one accelerated and
which did not. You may not be able to say wehtehr the acceleration is
due to externa; forces or gravity, locally, but you will know which
one accelerated.
The fact that acceleration is absolute shattered the dreams of
Relationalists. Actually, it is wrong to say "everything is
relative." unless dealing with very simple situations. In complex
situations, "things" are mostly absolute.
Pseudo intellectuals and nostalgics of dialectical materialism and
brutal marxism, along with some degenerates, some gays and lesbians,
still use expressions like "everything is relative". Einstein could
not escape the intellectual fashion of his time and adopted the term.
Yet, the world is absolute in many respects excpet for very simple,
idealistic cases. Whether pseudo-intellectuals, gays (have nothing
against them), lesbians (nothign against them as long as they do not
bother my woman), marxists, communists and other malfunctioning
organisms like it or not.
