Fair questions, but as I said, communicating the real answers to you is an issue.
I might have got this wrong, but your argument seems to be based on the fact that the theory of evolution does not postulate an underlying cause for its own process?
I’m not certain how you meant that question, but;
Evolution is a postulate of how things are occurring. It is not a postulate concerning any purpose involved. The exact opposite is the normal presumption of the evolutionist.
But in the real world of politics, evolutionists, presume to inject a thought concerning purpose. That is where they err most. And the purpose they interject just happens to be political relating to “Queen-Bee Socialism”. this is to say that we are to think that we exist only for the purpose of ensuring the hive - the government.
I happened to have a different answer to the speculation concerning purpose that just happens to fit the real scenario much better and also just happens to align with Christian thought. Note that I do not declare that I am Christian. But I have yet to find anything that Jesus ever said, that I could find in error.
I do not believe because I was raised to do so or because I feel it deeply inside. I am a “second testimony”, independent of the first that agrees with the first for Logical reasons entirely. Note that I almost never refer to Scripture other than to discuss a particular verse. And even then, I am usually challenging those who have accepted it so as to reveal their understanding of it.
So I have to ask two questions: Firstly - why MUST it have a cause other than itself? Why MUST there be a deeper purpose?
It must merely because it is observed to actually have it.
To understand that involves understanding what “purpose” actually means and how it ever comes about. That would be a pretty involved thread in itself. The end result from my thinking on that subject is that there is actually purpose being displayed in the sum of all reality.
Secondly - What’s your evidence for saying that this cause is God?I’m sure it would.
Merely because “God” is the word we use to name it.
But on the premise that (a) you’re not more intelligent than a significant subset of scientists (I mean that at face value, not as an insult), and (b) you’re not privy to some divine and unmistakeable insight that eludes the rest of the population of the earth - why haven’t smart scientists reached the same conclusion as you and started rejecting evolution publicly?
First, your presumption just happens to be less correct than you have presumed. Why do you presume that anyone you meet online is less than a scientist?
It is common to think, due to psychological reasons, that scientists are the “smart people” in the world. That is actually an absurdity. I have encountered many and have yet to find even one who could stand up and defend himself against any argument that I proposed to him. Of course, I don’t propose an argument that I do not already have substantial reasons to defend. In general, if you are arguing with me, you really will be found to be in error, but that isn’t because I am “smarter”. It is because I do not argue in presumption (or not often, sometimes I “play” or get sloppy

).
Why do you assume that everyone you meet online is inferior to those you apparently worship?
