Rigorous proofs are for mathematics. If you want me to provide a "proof" that your beliefs that life had a beginning then you'll be left wanting.
I want a sound argument -- but this is apart from the fact that I have also shown that I am not basing any of my arguments on a belief that life has always existed, as you earlier claimed in error.
Ok, life may be eternal. You might also be a brain in a vat only imagining your life. Both of those things are equally plausible but there is no reason to believe either of them.
Upon what basis do you equate their plausibility? We have observed life, and we have observed life existing for a very long time. We do not know that there is a first living thing. We're not really sure where "non-living" stops and "life" begins.
In contrast, we have never observed a brain in a vat imagining its life.
Clearly, your suggestion that these two propositions are "equally plausible" is totally without merit.
No, it is merely a possibility.
That doesn't contradict me.
Just as it is possible that your mother is/was a reincarnated Hitler. There are no reasons to believe either of those things.It's also possible that we are living in some teenagers video game too. Again, no reason to believe it. Since there is no reason to believe it then there is no need to consider it when making an argument.
There are real reasons to consider its possibility, as described above, but this is now a wholly different set of goalposts you've set up. The fact which I set out to establish is that the reasoning you'd described was terribly ignorant. Your concession is noted.
There is reasonable and there is possible. It isn't reasonable to believe that life has always existed.
Why not? Do you know a point in time when life didn't exist?
Again, no good reason to believe that it is true that life has always existed.
Repeating a bald assertion does not increase its truth value.
I think it is pretty obvious what you're doing. You're trolling. That is a very accurate description of reality.
...says the guy who continues to evade the questions he's been repeatedly asked.
So you're not sure if you're alive or not. D: To tell you the truth, neither am I now after these last few posts.
Good one. Now how about you answer the question?
Nope as in no you don't believe it or nope as in you do in fact believe it?
I don't believe life has always existed.
Open any Biology text book and you'll see it. Any of them will work for my purposes.
Do you think biologists have a rigorous certainty on what is and is not life?
There are no rigorous definitions of what life is.
Then what definition are you claiming I should find in a biology text? The definition you're now admitting doesn't exist?
That doesn't mean we can't talk about it in meaningful ways.
But it does mean you can't be certain when or if it began to exist.
Rigorously define every word in that statement. Otherwise it is far too ambiguous to make any sense of it.
It appears now that you have forgotten how to speak English. It is no wonder you struggle with more difficult concepts like life.
Gainsaying. Is that really the best you can do? Are you that desperate to avoid conceding your errors?
Open your Biology text book.
I didn't find it. You tell me. You can, can't you?
No, you'll need to choose one out of any Biology text book. That is not a good definition to what life is.
So when you said it was irrelevant, were you lying?
Not a good definition. But you're right it can't be just any definition, point taken.
So you have been caught lying. Why should anyone believe anything you say?
No, not really. But I was only talking about the most accepted definitions of life. Not some absurdity like you've created. That's why I'd like you to open a text book on Biology.
Why do you think it is reasonable to suppose that such a contemporary and unresolved issue could be so easily resolved by reference to any old biolofy textbook. Do you even understand how academia works?
You were the one purporting to know. You answer that question.
It is more likely than not.
Based upon what calculations?
If we need certainty to discuss anything then we may as well shut up, because there is very little of it to go around.
You were the one speaking in certain terms. You are, naturally, invited to shut up at your earliest convenience.
LOL. Nobody thinks replication has been going on for eternity, much less anybody in this thread. You've based this entire thing on the possibility that it has been while not providing any reasons to take it seriously.
I provided several reasons in this very post, reasons which should have been common knowledge to anyone that has ever read a National Geographic.
It isn't like I said gravity repels people away from mass.
No, you said something more stupid, akin to "circles have pointy corners."
Everybody here thinks that life didn't exist in one point in time.
I don't.
There is no reason to consider it, there is no reason to refute it, and there is no reason anybody should take it seriously.
The fact that we cannot find a first living organism is a pretty good reason.
I think that will do on the subject. I've wasted enough time with your trollish behavior. I won't respond further about it.
Yes, you will bow out, and concede defeat. Next time you have no idea what you're talking about (which I'm sure will be soon) you might consider keeping your stupid false arguments to yourself, and then we won't have to endure your continued embarassment any longer.
