Because every science course I’ve taken so far has left me even more confused than ever.

This reminds me of the question at the dinosaur museum asked by a visitor to one of the staff.
“How old are these dinosaur bones?”
And the answer the staff member gave was
“66,000,004 years”
“How do you know the exact answer, to the year?”
“Well, when I started working here four years ago, the bones were 66 million, so now they must be 66,000,004 years”
This is why scientific notation is important, because we know the actual answer is only significant to two digits, 6.6×10^7 so the actual age of the bones could be anywhere from 65-68 million years, and isn’t known to be exactly 66,000,004 years old.
Just like how there are 8 billion people on the planet. When your sister’s child is born, that doesn’t make the population of the planet 8,000,000,001 when the actual population is 7.753×10^9
