Are you pro-science or anti-science? Raw meat isn't necessarily bad or fire terribly scientific.
Observation of natural wildfires:1) By standing not too close and not too far away, one can stay comfortably warm when air is cold.
2) Fire is found only on wood or grass.
3) Fire consumes wood or grass.
4) Fire seems to spread to new wood when in contact.
Experimental verification: place more wood on fire and observe that fire always spreads to new piece of dry wood or grass.
Hypothesis: Heat can be obtained by keeping fire “alive” in a non-combustible area.
Experimental Verification: Carry burning stick to cave and feed it with new wood.
Further observation of natural wildfires:5) Meat from some animals killed by fire is good—tasty, juicy, and easy to chew.
6) Meat from some animals killed by fire is not good—tastes like bitter old wood, no juice.
Hypothesis: Just the right exposure to fire makes meat good.
Experimental verification: put meat on stick next to fire and see what happens. Remove meat when juicy. Enjoy.
Conclusion: “Science” is a natural process of the human mind—at least for some human minds.
