How to GetChildren() of many parts at once?

Very messy but i do not now how to write "Spawn", i want to have all the spawn0 - spawn6 in a single line

    local Spawn0 = game.Workspace.Map.Normal.spawner:GetChildren()
    local Spawn1 = game.Workspace.Map.Normal.spawner1:GetChildren()
    local Spawn2 = game.Workspace.Map.Normal.spawner2:GetChildren()
    local Spawn3 = game.Workspace.Map.Normal.spawner3:GetChildren()
    local Spawn4 = game.Workspace.Map.Normal.spawner4:GetChildren()
    local Spawn5 = game.Workspace.Map.Normal.spawner5:GetChildren()
    local Spawn6 = game.Workspace.Map.Normal.spawner6:GetChildren()
    local Spawn = (Spawn0, Spawn1 , Spawn2, Spawn3, Spawn4, Spawn5, Spawn6) --?

the reason im wanting all in spawn is for the following line:

for i,model in pairs(Spawn) do
        local enemyHuman = model:FindFirstChildWhichIsA("Humanoid")

so the zombies spawn in game.Workspace.Map.Normal.spawner, game.Workspace.Map.Normal.spawner1, game.Workspace.Map.Normal.spawner2... etc. and i need it all gathered for this turret im making

Please provide explanation with your answers. Simply posting code does not spread knowledge of integral scripting processes which helps people understand the logic and reasoning behind your answer.
local zombieNum = 0 -- to make the difference
local spawns = {}
for _, spawn in pairs(workspace.Map.Normal:GetChildren()) do
    for _, zombie in pairs(spawn:GetChildren()) do
        if zombie:FindFirstChildWhichIsA("Humanoid") then
            spawns["zombie"..zombieNum] = zombie
        end
    end
end

By using a for loop, this should be relatively easy.

First, we grab the parent of all the spawners, in this case, workspace.Map.Normal.

Then we put it into a for loop, looping through everything inside that parent, searching for Humanoids, since I assume only zombies have that inside workspace.Map.Normal. This can be accomplished with :GetDescendants(), which gets the child, the child of the child, the child of the child of the child, etc. under the instance.

After that, put it into a table.

In case new zombies spawn, we want to add them to the table too, so whenever a descendant is added, we add them to the table. Whenever a descendant is destroyed/removed, we take them out of the table.

Now the zombies table will contain any zombies spawned and is still alive.

local zombies = {}

for _, v in pairs(workspace.Map.Normal:GetDescendants()) do
    if v:IsA(‘Humanoid’) then
        zombies[v.Parent] = true --puts the model the humanoid is in into a table
    end
end

workspace.Map.Normal.DescendantAdded:Connect(function(descedant)
    if descendant:FindFirstChildWhichIsA(‘Humanoid’) then --if it’s a zombie
        zombies[descendant] = true
    end
end)

workspace.Map.Normal.DescendantRemoving:Connect(function(descendant)
    zombies[descendant] = nil --if the descendant is in the table, it will be removed, else this wont really do anything
end)

Quick edit: This table is a dictionary, so in a for loop, you need to use the index part, not the value part.

--example
for zombie, v in pairs(zombies) do
    --zombie is the actual instance, and v is just a placeholder
end
