A few questions

[Ben Davis]

Hi Vivalarevolution,

...what about the opinion that the universe was designed by an intelligent designer/ architect/engineer doesn't make sense.?

That there's no reliable evidence to support this position. I'm also interested in what attributes you would attach to this 'designer'. Is it a theistic god? A deistic god? An incompetent engineer at a CERN reactor in another universe?

Can you 100 % be certain of the scenario that it isn't this way?

Can you be 100% sure that it is? That's clearly a loaded question. Certainty isn't the issue as we can never really be 100% certain of anything. All we can know is what the facts tell us, what the likeliest interpretations are from the preponderance of evidence. As new evidence is uncovered, as our knowledge grows, our interpretations are updated thus becoming more accurate. Do you acknowledge the prudence of that methodology?

If you can't, you would be agnostic.

Indeed. In terms of intellectual honesty, I'm happy to admit that I'm agnostic, ultimately. That doesn't make me any less of an atheist.

Can you say for SURE that we are the cause of our existence is that the universe just HAPPENED to start with the big bang, stars formed, chemicals formed, planets etc . . . are we to give credit for our existence just to luck?

'Luck' is the wrong word. 'Happenstance' is better: the conditions were such that the big bang occurred, stars formed etc.

Because if the universe worked in any other way than it did in the past 13.7 billion years . . . It's safe to say we wouldn't exist.[quote]
Not necessarily the tautology it seems. There's been some research done which indicates that the fundamental forces of the universe could operate differently and life would still be possible.
[quote]So out of the infinite possibilities of what could have happened, we have a star created from a molecular cloud collapse, 4.57 billion years ago, planets got created. If even one planet out of 8, (except maybe mercury) would never have been created, earth wouldn't still be the same distance from the sun (and our position right now is perfect).
These conditions were necessary for life. Why out of the infinite number of other possibilities, like what if dark energy really didn't / doesn't exist to expand the universe with the same "force" (I can't think of a better word) it does now?

We don't know that the possibilities are infinite. It's possible that the fundamental forces of the universe can be no other way than that which they are (e.g. they could be described by the systems which gave rise to the big bang). In which case, life would be inevitable.

Logic, and laws dictate that there should've been multiple future possibilities. And since you proved chaos, there was no reason for things to happen as they did. And yet they have. Out of the multiple future possibilities, we HAPPENED to come to life.

What logic and which laws?

Luck?

Happenstance.

PS- I really would love to know if there were multiverses where they work different to our universe . . . How their systems formed, if and how life evolved there and how life evolved when the properties of the multiverses were different from ours. Really exciting field!

Indeed! Of the various models proposed, I'm a fan of the one where every possible alternative is played out. I don't know if that's what actually happens but the idea of infinite phase-space is appealing to me.
