It wouldn't convince any rational person.
what woudl convince a rational person
Neither of you have really addressed the important questions:
- how would you know that the spectacular single event - whatever it is - is actually God?
The event described in the OP could only be explained by intelligent design. Since it would be very unlikely that just by chance the stars happened to form a pattern that looks like meaningful words and sentences.
The God of the bible would be the best explanation because of Okams Razor, any other God or intelegent design hypothesis would require an additional assumption “that the designer lied and tried to fool us”
as an analogy
Imagine that you receive a whatsapp message that says “hey I am your neighbor John from apartment 102 just to let you know that I changed my phone number, if you need anything please contact me on this number”
how would you know that your neighbor John wrote the message ? well obviously you cant know for sure, maybe someone is trying to fool you, but okams razor says that you should prefer the John hypothesis over any other hypothesis” because any other hypothesus requeries adition assumptions ………..so the same applies to the message in the OP you should prefer the Christian God hypothesis over any other hypothesis because of Okams razor,
So in summary, granted I wouldn’t know for
sure that The Christian God did it , but it would be the best hypothesis
- why wouldn't we see evidence all the time for a god who's supposedly there and active all the time?
The evidence that we currently have is good enough to convince 99+% of the world’s population that has ever lived………….and given my experience with atheists no amount of evidence would ever convince most of the remaining 1% anyway.
Every time new evidence is presented, all atheist do is raise the bar higher and become more skeptical….. I mean honestly if we fInd 10 independent documents written by different people (romans, Christians, jews, etc.) from the first century confirming the empty tomb, and the post mortem appearances of Jesus, would that convince you that Jesus rose from the dead, or would you simply become more skeptical and reject those sources for whatever reason?
