Leviticus chapter 9

After reading Leviticus chapter 9:

*On the eighth day after the ordination of Aaron and his sons, Moses summoned them and the elders of Israel. He told them to make a sin offering with a goat, a burnt offering with a calf and a lamb, a fellowship offering with a ram and an ox, and a grain offering. They gathered up the things for the offerings and met at the front of the tabernacle. Verse 5 says the entire assembly came near and stood before the lord. Does that mean all million plus people? That must have been some crowd in front of the tabernacle. Moses told Aaron to make the offerings. They were done according to previous instructions. Then Aaron lifted his hands and blessed the people. How much power do you think that blessing had over those people's lives? After that, Moses and Aaron went into the tabernacle, presumably to consult with God. When they came out, they blessed the people again, and the (indescribable) glory of God appeared to all the people. Fire came out from the presence of the lord and consumed the burnt offering, which had already been burnt in verses 12-14, and again in verse 16. I'm confused. Anyway, when the people saw it, they cheered and fell facedown. Did the people in the back of the crowd even know what was happening?
