I have a dear friend I've known for years. In a recent she mentioned prayer. I disclosed for the first time, that being the first opportunity come up, my atheism. Yesterday, we had a long discussion back and forth. Short texts, nothing lengthy. She sent me the following text just this moment, she wants chat later. "I have get ready go a dinner with family. But where did the universe come from have the big bang? It couldn't come out of nothingness." Does anyone have a good, concise, respectful answer. I don't want be mean her. Maybe you guys can help. Thanks. **** update
Thanks to my friends on this site, I think i came up with an acceptable explanation. Took a screenshot. I suppose we agreed to disagree.
No god is needed to explain the universe. Potential energy/energy has always existed. There is no reason to give this energy self-awareness/consciousness, will/volition, or any other human attributes. Energy sometimes becomes matter, matter sometimes becomes a living thing and sometimes a sentient being; and matter returns to an energy state.
If she can say that a god, that is complex enough to create everything, has always existed, why is it such a leap to acknowledge that all this complexity can exist without the need for a god to have created it?
You can think of the Big Bang as a phase change, in some ways akin to the boiling of water. It is not that there was nothing, it is just that here is nothing on this side of the phase change that can give us any inkling of what is on the other side of the transition. Or this could all be BS.
Here's a video about how a universe can come from nothing, and how our universe is consistent with that model:
I would add that there is a tendency when we don't understand something to answer it even if we don't have an adequate response. While we don't necessarily have a concrete answer about the origin of the universe, we shouldn't give into the temptation to provide another answer that explains nothing. To do so is no better than to say, "it's magic."
As unsatisfying as it is, "I don't know" is a valid answer. If there is no knowledge, then be honest instead of making something up. I am sure you can make that more tactful, but that is the gist of it. We don't know if a god or gods exist either. People can believe in it, but there is still a need for proof before you claim knowledge (without getting too deep into how to know if you can know anything or if reality is real, etc.).
If nothing can come from nothing, then where did this infinitely complex, infinitely powerful being come from and what is he made of? If this being and the stuff he is made of could come from nothing, then so could the universe and the stuff it is made of. That would mean that no creator is required.
All any of us knows is that the universe is expanding, so we assume it may have been all in one place once.. that's all we know, but scientist build math models based on their assumptions that makes predictions of other phenomenon we can see and measure. It doesn't mean it's how it is, it just makes it more likely.
Simply telling you the universe couldn't come from nothing doesn't answer anything. All it tells you is the universe couldn't come from nothing, it doesn't tell you God did it, it doesn't even tell it's more likely God did it because we know nothing about what was before the Big Bang to assume it's more likely God did it. Simply saying God did it because there is no other known explanation of how the universe came about is an argument from ignorance which is logically fallacious.
