I'd say the reason is that I have not seen any empirical proof of other<br>
life-comptaible universes, and therefore, they don't seem pretty real to<br>
me at the moment.<br>

Yes, I think that is the crux of the issue here. For physical objects,<br>
inferring is strong, but verfying it, is stronger. I'd prefer the<br>
possibility to verify it over infering.<br>
<br>
But this is physical objects only.<br>
<br>
When taking the step from physical objects, or by extension, our<br>
universe, to god or multiple universes, I'd very much not trust<br>
inference, but would very much like to verify.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">Trust but verify. 😉</div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Got it. No, my opinion is that it is not empirical. It is an attempt at<br>
explanation, but not proof. Does the explanation have some kind of power<br>
of prediction? </blockquote></div></div><div dir="auto"><br></div><div dir="auto">Perhaps this is the role filled by abductive reasoning:</div><div dir="auto"><a href="https://en.m.wikipedia.org/wiki/Abductive_reasoning">https://en.m.wikipedia.org/wiki/Abductive_reasoning</a></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Does it help me become a better person?

True, it may do so, but my reasoning I think, remains the same.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">Well perhaps this is the evidence you're looking for. If we, say, discover a glider in the GoL universe and then copy it and paste it into its own GoL space where it can enjoy gliding forever, then here is an example of "someone" whom underwent the procedure, so you know it alcan and does happen for some entities.
