The earth rotates once every 23 hours 56 minutes something and revolves once every 365 days 1/4 days (to be precise, 365.2564 days). Try to proofread your question properly?

Meanwhile, to prove it you can simply observe. To tell the truth, even scientists "invent" those values. In particular, the "mean solar day" of exactly 86400 mean solar seconds is obviously invented from ancient people dividing time in a day into 24 hours, each divided into 60 minutes, each divided into 60 seconds.

Earth rotates once every 23 hours 56 minutes due to that day and night happens. And Earth revolve once around the sun in 365 days and 1/4 hours due to that many season happens like summer,winter etc. This is very simple proof for ratation and revolution of Earth.
