I am trying to regen the players character when the player touches the part Sand. Help?

local player = workspace:FindFirstChild("Player")
local ResetPoint = player.Position
player.Position = Vector3.new(ResetPoint)

if game.ReplicatedStorage.GravityController:Destroy() then
    local part = workspace.FindFirstChild("Sand")
    part.Anchored = true
    part.Parent = workspace
    part.Touched:connect(function(hit)
    local hum = hit.Parent:FindFirstChild("Humanoid")
    if hum then
        hum.Health = 0 
    end
end)
end

if hum.Health = 0 and game.ReplicatedStorage.GravityController:Destroy() then
    player.Position
end
