OK, I have a question for you to start off.
Is there anything that exists without a purpose for its existence?
If yes, explain what it is and why it has no purpose.
If no, you must concede the universe has a purpose for its existence.
I think there are two serious confusions here. First:
Are you saying, as Aristotle did, that nothing in nature is without purpose
? - eg. An eye has the purpose of seeing, the sun has the purpose of shining etc... If this is what you mean then it seems to me that the claim is unfalsifiable as the claim that everything in nature is without purpose
could equally be held to be true - eg. it is true that nn eye sees
and the sun shines
but they do not do so for some external goal.
Unless you can point to something which allows us to say that purpose
is an inherent characteristic of objects we cannot resolve the issue either way. If we think about this it is obvious that we will never be able to resolve this as purpose is not a necessary connection between objects
. It is only a connection that can be drawn by the mind (if you disagree can you provide an example when this is not true?) and thus we cannot prove one way or another if the connection is necessary
to the object (ie that it is objectively 'there').
So in answer to the question "Is there anything that exists without purpose for its existence?" we must
(if we are honest) respond that we do not know - a forteriori
that we cannot
Even if I grant you that everything within the universe has purpose (and for the reason above I wouldn't); that does not logically entail that the universe itself has purpose. The universe is the set of all things
- it is not itself a thing. If it were that would lead to a paradox as being a thing it is/can be causally connected to other things, and thus is within
the net of all causally connected things (ie the universe). The universe cannot both be a collection of all objects, and itself an object!
To use an analogy: Just because every human being has a mother it does not entail that humanity has a mother (as "humanity" is the set of human beings not a human being itself!). Similarly; just because every object has a purpose that does not mean that the universe has a purpose (as "the universe" is the set of objects not an object itself!)
hope that helps clarify
