Angel in church?

While at church today, the pastor was preaching about God. I was paying attention to the word that was being said,when I look over to see a oval white orb come out of the floor and fly to the ceiling of the church. I’m not sure what it was at the time, until I looked up the meaning on Google saying that it was a spirit or an angel. Honestly I’m not really sure what it was during the time, but it’ll be nice to have other input on this type of experience.
