I never fully understood how a simple flush of a few litres of water sends all my poop and toilet paper to the sewers. If the main drain is in the basement 10 feet below the surface, does that mean the sewer lies further below the surface? I would love to see a video on what actually happens when you flush the toilet. TIA.

All plumbing requires a certain amount of downward slope to allow things to naturally flow. When you flush the toilet, you actually use quite a bit of water, contrary to what people might suggest. This is enough water to get stuff out to the street where the sewer main is without much issue.
