"The greatest deception men suffer is from their own opinions" - Leonardo da Vinci
"I think I use the term “radical” rather loosely, just for emphasis. If you describe yourself as “atheist,” some people will say, “Don’t you mean ‘agnostic’?” I have to reply that I really do mean atheist, I really do not believe that there is a god; in fact, I am convinced that there is not a god (a subtle difference). I see not a shred of evidence to suggest that there is one ... etc., etc. It’s easier to say that I am a radical atheist, just to signal that I really mean it, have thought about it a great deal, and that it’s an opinion I hold seriously." - Douglas Adams (and I echo the sentiment)

So I guess he should have said it. We know now we are apes but did Darwin ever say that humans were apes?

Not really. There had next to information on human ancestry during Darwin's time.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.

MM
But humans are apes.
Yes, but that could only be definitively and unambiguously said under a new overarching system of classification of organism developed in the late 20th century.
Prior to that it was recognized humans and apes shared a recent ancestor, but whether humans themselves ought to be considered apes remained an open question, without a universally accepted definition of "ape" to adjudicate the answer.

Whether we are apes depends on how "apes" are defined. You'd be surprised how inexact an art animal group definition and classification had been until late 20th century.
We had a reasonably accurate picture of how different animals such as chimps and men might have been related long before we developed a theoretical framework for rigorously classifying different organisms based on ancestry. Prior to this classifications were based on comparative anatomy rather than ancestry, and it was largely subjective what anatomically distinctive traits were important enough to give an group of organisms a separate grouping of its own. Prior to modern cladistic classification, the combination of bipedalism, tool use, and large brains were considered by many to enough grounds to put hominids into a separate group from apes. In this system, hominids and apes were sister groups sharing an common ancestor. But hominids were not apes.
Darwin would have been familiar with classification by comparative anatomy, but would not have known cladistics. So he would have know calling humans apes would not only be controversial, it would not have received universal backing of all those who otherwise would agree with him on common human and ape ancestry.

Good ol phylogenetic cladistics. The fact that twin taxonomist would likely argue about who there own mother doesn't seem to help the creation crap fest.

Yeah, I got this..
My biggest hobby in life is studying evolution, the history of evolutionary theory, and the biological history of man.

Observed birth of new species through common ancestors and even birth of multicellular life.

This is true. I only say we are apes because animals don't grow out of their evolutionary ancestory. Like we are still chordates and vertebrates and tetrapods. So you can say we are apes or just a subset.
