Is there empirical evidence for dark matter and dark energy?

Is there empirical evidence for dark matter and dark energy?This thread is intended to determine with precision what if any is the empirical evidence ascertaining the existence of dark matter and dark energy.For the background of this thread see [click line in bold] Thinking outside the box of empirical evidence, where Percy says that there is empirical evidence for the existence of dark matter and dark energy, and I am asking him there to show the empirical evidence establishing the existence of dark matter and dark energy.My own position is that prescinding from the existence of socalled dark matter and dark energy -- and I for one am certain that dark matter and dark energy do exist, the way people propounding their existence is not because they have empirical evidence.And I want to know on what basis if not on empirical evidence these people say that there are dark matter and dark energy.For myself, how do I know that dark matter and dark energy exist?I know that they exist from intelligent thinking.But I am sincerely very interested with an absolutely open mind -- which is open to receive substantial new ideas and also open to let go of false ideas -- to hear from people who have empirical evidence for the existence of dark matter and dark energy.Yrreg

The title of this thread as given by me is:

And the way I understand the title is conveyed in the following sentence also in my own words:

Wherefore in other words:

So, let us just keep to factual existence of empirical evidence proving the factual existence of dark matter and dark energy.I gave the example of empirical evidence for the existence of the nose in our face from the fact that I touch the nose in your face and you touch the nose in my face.And please, no need to bring in the word proposition, just keep to facts.Yrreg
