I am not sure what the context is here. Were you on a date?

The difference between atheist and agnostic for most people is just a bit of semantics. Hardly anything to get fired up over. Most agnostics don't care enough about the existence of a god to alter lifestyle or mindset, and most atheists will not claim a 0% chance of the existence of god. Even this website has a 99.9% choice as to your opinion on the chance of god existing.

You can't prove a negative. There is a greater than 0 chance that santa, bigfoot, unicorns, fairies and gods exist. The universe is a big place and we can't search it. I am confident the odds are crazy low for all these entities.

I use the term atheist for myself for 3 reasons:

1. Agnostic makes most people think you are 50/50. I am not. I am very close to zero % on god's existence.
2. Definition of atheist implies a lack of belief. Not having an invisible friend is my natural state. Belief takes effort, it is an activity I do not participate in.
3. Part of the social issue that freethinkers have is that we think freely. We are not a united group, it is like herding cats. It is our strength and our weakness. We go by many names, have a diverse philosophy and choose to express our opinions openly and freely. I say I am an atheist because it is better defined and opens up discussion, though often it is just people telling me I am stupid. The irony of that both funny and sad at the same time.

Hope this was helpful.

Depending on the level of indoctrination there can be several stages on the way to atheism. Some people get stuck in one stage and are unable to move on. First one questions one's own beliefs (as imposed by others). Then one questions the beliefs of others. Then resentment and anger at being indoctrinated since childhood before one could make a cognitive decision. There can be a desire to disprove 'god' and this is when aggresive evangelical atheism can occur, atheism becomes the 'religion' and converts are sought. (This is the stage many get stuck in and i believe that is the type of person you encountered.) Eventually the question of 'god' becomes an irrelevance to one's life. That's when you are a true atheist. Obviously this is a very simplistic explanation. Everyone's personal journey is different and many factors come into play. ?

Maybe the person had asperger. They ramble like a teenager on their first date trying to impress. I don't know why I am rationalizing. I like to think people are generally good. I sound like "Ann Frank". We know how that worked out for her. I do know you just keep trying and with any luck it will happen for us all. Good luck

It can happen. Particularly when the real world is kind of hitting us harder than usual.

But for the most part we really do rub along pretty darn well - and we like each other - which is even better.

Pretty sure you came here not believing what you already not believe - and I'm good with that.

There have been some fakes out there. Hang with it there are a lot of intelligent people on here.

I think everyone you come across will be different, whatever flag they fly.

Communication isn't dependant on everyone thinking the same. If you and this person weren't communicating effectively despite the differences, maybe the next experience will be better. Or worse.
