How do I stop this script from breaking after being touched by anything other than a player?

This script is for a random weapons crate in my game, however I also have aliens roaming around. When one of these aliens runs into a weapons crate the script instantly breaks with the response : "Alien is not a valid member of Players." How would I make it so that if anything other than a player touches it, the script doesn't break?

script.Parent.Touched:connect(function(hit)
 script.Disabled = true
 
local player = hit.Parent.Name
local random = math.random(1,100)

if random > 0 and random < 23 then
 local laserSword = game.ServerStorage.LaserSword:Clone()
 laserSword.Parent = game.Players[player].Backpack
 
elseif random > 23 and random < 61 then
 local sCAR = game.ServerStorage.SCAR:Clone()
 sCAR.Parent = game.Players[player].Backpack 

elseif random > 61 and random < 100 then
 local weapon7 = game.ServerStorage.Weapon7:Clone()
 weapon7.Parent = game.Players[player].Backpack 
end

script.Parent:Destroy()
end)

    end

end)

here is an easy three lines:

if not game.Players:GetPlayerFromCharacter(hit.Parent)
	return
end

now, if you want it IN THE CODE, here:

script.Parent.Touched:connect(function(hit)
	-------- CHECKING FOR PLAYER... --------
	if not game.Players:GetPlayerFromCharacter(hit.Parent)
		return
	end
	-- If the script continues from here, the player is not nil.
 script.Disabled = true

local player = hit.Parent.Name
local random = math.random(1,100)

if random > 0 and random < 23 then
 local laserSword = game.ServerStorage.LaserSword:Clone()
 laserSword.Parent = game.Players[player].Backpack

elseif random > 23 and random < 61 then
 local sCAR = game.ServerStorage.SCAR:Clone()
 sCAR.Parent = game.Players[player].Backpack 

elseif random > 61 and random < 100 then
 local weapon7 = game.ServerStorage.Weapon7:Clone()
 weapon7.Parent = game.Players[player].Backpack 
end

script.Parent:Destroy()
end)

    end

end)
