Unlike you - who denies, for example, that the SN1987A explosion ever
really happened (since it took place about 168,000 years ago) even
though we witnessed the stellar explosion - I haven't clenched my
eyes shut from seeing what there is to see!

this kind has been made.

species came along that was capable of making advanced technology,
and this itself was due to a number of historical contingencies. And
in astronomical observation of our galaxy we have actually observed 0
(zero) Earth-like planets (we don't even have the technology to do
any kind of survey as this). Maybe we are the first technology-
producing life form in our galaxy. Maybe not. Who knows?
At least you didn't try to misrepresent the Drake Equation in this
post, as has been your habit previously.
It's kind of fun watching you build sandcastle arguments in the air
