1. It doesn't matter which religion "outweighs" the others: What is important is which facts about reality are TRUE. Religions come and go; Christianity is the most popular NOW, but previously, Judaism and paganism were the most popular. It didn't make them true. Islam is the fastest growing religion and will outweigh Christianity later this century: It still doesn't say anything about which religion contains truth.
2. YOU believe that something can happen without a creator: God. If you believe that God, an intelligent being with emotions and willpower, following the rules of logic, can exist without being created, how come you find it hard to believe that the Universe wasn't created either, when it is not intelligent and doesn't posess willpower, but still follows logical laws. It has 2/3rds less complexity judging by those 3 attributes, so is more likely to exist uncreated than a God is.
3. It doesn't matter how 'pointless' I think things are, nor how the truth makes me feel. The truth is the truth, and my human emotions can't change whats true. In other words, even if I really felt that I needed a god to exist in order to give my life meaning, it wouldn't mean that there was actually any real gods aside from in my mind.
4. I have no issues with love; love is great.
5. Your comment about Julius Ceasor is crazy: Many hundreds of writers at the time and since wrote about him, whereas NO authors in the first century wrote about Jesus from first-hand knowledge. And, saying that "everyone believes" is informative is wrong: Everyone once believed the Earth was flat, too. They were wrong.
6. Your comments about suffering do not explain why god would have made suffering in the first place. For summary of such arguments see: "Introduction to the problem of evil" by Vexen Crabtree
7. Christmas is heavily pagan - mostly a collection of sun-worshipping practices - which is why some hardline Christian churches ban their members from celebrating it. Same with easter; an ancient pre-Christian fertility festival. But just because they are pagan, it doesn't mean that paganism is, or should, be true. You can't argue that because you like some human festival, the religious causes of it must be true, that's just wishful thinking and not a good basis on which to form beliefs.
8. Christianity held back medical science for hundreds of years - pagan Greek physicians and the middle eastern doctors remained far advanced of Christian priests, who suppressed secular knowledge even in colleges and universities. The NHS would have been founded earlier and on better science if Christianity WASN'T true, so I don't see why you mention it.
