(Buddhists believe in rebirth. Buddhists also claim that there is no chronological first beginning to the series of past lives. We have all of us been reborn an infinite number of times. No God is needed to start the series off – for there simply was no first beginning. Things have been around (somewhere) for all eternity.)
We need to understand why God as a creator cannot exist. There is a deep analysis for this. The reason is not because there is no beggining then there is no god. The reason is because of emptiness of inherent existance. In case you have understood this concept, you will be able to tell why it is impossible for God as a creator to exist.(If rebirth is true, realistically we really have no hope. It is a hopeless doctrine.)
I think because there is rebirth, there is hope. Imagine if we are in the hell and there is no rebirth. It will be end of the world, because forever you will be in the hell. Buddhism doesn't accept permanance concept. Consequently, our stay permanently in the hell is rejected. SO, there is big hope to reborn again and again until finally we stop this reborn. Rebirth is beautiful, isn't it? It gives us unlimited chances to be a Buddha.(I cannot imagine being reborn as a stinkbug precisely because there is nothing to imagine. I quite simply would not be there at all. If rebirth is true, neither I nor any of my loved ones survive death. With rebirth, for me – the actual person I am – the story really is over. There may be another being living its life in some sort of causal connection with the life that was me (influenced by my karma), but for me there is no more. There is no more to be said about me.)
My comments will be similar with above comments.(If Buddhism is correct, then unless I attain enlightenment or something like it in this lifetime, I have no hope. Clearly, I am not going to attain enlightenment in this life. Many of you will be inclined to accept that as true about myself and about your own enlightenment, as well, since enlightenment is a supreme and extremely rare achievement - not for the likes of someone like me. So I and all my friends and family have in themselves no hope. More than that, from a Buddhist perspective, in the scale of infinite time, the significance of each of us as such, as the person we currently are, converges on nothing - for each of us lives our lives and then perishes. Then we're lost forever.)
This feeling I think is quite common. In Lamrim, it is explained that in case we cannot achieve enlightenment, it is fine, but at least we have to be able to be reborned again as human. There are conditions, which will condition us to be reborn as human and they are explained in Lamrim. So, don't worry about it.
In case, you think you can exceed that requirement, then you can try to find what is emptiness both at intellectual and direct experience level. It is this understanding of emptiness which free us from reborn. So, you just need to put your whole energy into this key term called emptiness.
There are numerous meditation method you can use to understand it. Find something which is suitable for you. If I can give a suggestions, you can look into this 4 books to get a good understanding about meditation and how to practice it both during meditation and after meditation:
1. Mindfulness in Plain English.
2. Natural Liberation.
3. Vivid Awareness.
4. The Flight of Garuda.
Once we understand the technique well, we can have a feeling actually enlightenment is not difficult and it is not something very far away from us. The difficult part is do we want to practice it or not? How can we be effective in our training?(Again, if rebirth is true, we really have no hope. It is a hopeless doctrine.)
Do you still think rebirth is hopeless?
