Why does "table.find()" returns a nil value inside of a table of players?

I am trying to find the index value of Hit.Parent, inside of a list of players. However, it returns me nil instead of the index value.

local Players = game.Players:GetChildren()
RedSide.Touched:Connect(function(Hit)
	print(table.find(Players,Hit.Parent))
end)

Any ideas on how to get the index value of this working properly?

Thanks!
