The meteor impact cause of extinction is conjecture. I wish the word “scientist” wouldn’t be used in concert with the words “could be”, “consensus” or “experts think”.
And I thought life on earth was all happiness, butterfly wings, and having perfect stable climate before evil conservative deniers began driving their mega polluting suvs and started fracking-say it ain’t so that climate/environmental change has been a given constant-oh the humanity
A hypothesis is a “could be” statement whatever you think of it. “Maybe” comes before the fact gathering, analysis and proof. Curiosity is the backbone of science.
