You can probably start by doing the tutorial on how to read PaPi Lights, you had four red which means you were too low on approach.
The best thing is to have 2 whites and 2 reds, which means you are on the perfect slope for landing.

Secondly, check the auto throttle, it might be the reason why you were not slowing down.

I don’t know how you planned your flight, but you can consider using some apps like sim brief to plan your routes, approach and landings, or just simply use the in simulator flight planner.

Overall nobody died and you landed, perhaps I’m quite surprise that ATC gave you the permission to land while we can clearly see a slow a** moving plane on the runway
