I agree with your thoughts that your message "fossil fuels = humans flourishing" isn't clear.

Maybe try this:

start out with your conclusion -- fossil fuels= human flourishing.

Then provide a few points about why fossil fuels = flourishing ... Energy is fundamental to everything we produce, thus raises std of living

Fossil fuels are low cost, on-demand, versatile and scale

They've improved health care, raised living standards, improved ability of man to deal with climate related disasters...

Allowing man to master nature....

Then show statistics (or animated chart) to prove your point ---lower world poverty levels.

Then show impact of political motivated narratives and how they sway opinions from reality .

Conclude: life is good ✨🙏
