How to check if 2 Vector3's intersect with eachother?

The title says it.

How would I check if two Vector3 values intersect with each other? Note: I will not use raycasting since it is a vector and not a part, so don’t get confused.

I haven’t tried doing anything yet because I knew I was going to fail every time. I also didn’t find anything that suited my needs on the Roblox Developer Forum.

Use both of Positions and use one of these ways

while wait() do
      if workspace.Part.Position == workspace.Part2.Position then
           print("Instersected")
      end
end

or

while wait() do
     local magnitude = (workspace.Part.Position - workspace.Part2.Position).Magnitude

     if magnitude <= 1 then -- Instead of 1, put whatever number you want
           print("Instersected")
     end
end

EDIT
I have tried the answer given down below and it doesn’t work, when I run the code it doesn’t print anything, I don’t know why.

I recommend using a BoundingBox and then get a list of descendants, then check each descendant to see if it is a part and if it is a part then check the BoundingBox.
Also, please use code tags.
I recommend trying something like this
–[[
When you run this code, if everything goes correctly, it should print
“Intersected”
]]

local bb = Instance.new(“Part”)
bb.Name = “BoundingBox”
bb.Size = Vector3.new(1,1,1)
bb.Position = Vector3.new(0,0,0)
bb.Anchored = true
bb.CanCollide = false
bb.BrickColor = BrickColor.new(“Really black”)
bb.Parent = game.Workspace

local part = Instance.new(“Part”)
part.Size = Vector3.new(1,1,1)
part.Position = Vector3.new(0,0,0)
part.Anchored = true
part.CanCollide = true
part.BrickColor = BrickColor.new(“Really black”)
part.Parent = game.Workspace

local bbDescendants = bb:GetDescendants()

for i,v in pairs(bbDescendants) do
if v:IsA(“Part”) then
if v.BoundingBox:Intersects(bb.BoundingBox) then
print(“Intersected”)
end
end
end
