It's often difficult to start a dialogue between eastern and western religions. Moreso with Christianity and Islam, who are more fixated on the need to convert people to their one absolute truth which comes from the one true god. Judaism doesn't care about converting people, though still believes in the one god, whereas eastern faiths are much more potluck about this sort of thing. The core of Buddhism isn't even really a religion as such. The more religious aspects of Buddhism were tacked on later, mostly through the Mahayana path, which added in heavens and hells and beings such as Bodhisatvas.

Well, yes, this alone differs from other religions, in that many do not recognize a God at all, or their conception of God is far different from that of the Christian.  Which brings me to the point - a Christian, in order to be worshipping God, must have in their mind the correct conception of God; this is what the majority will tell you (and Paul would confirm this).  A correct Christian belief requires acknowledgment of the Trinity (for some, the Trinity is replaced by other doctrines, but these are certainly not the mainstream) and submission to it.  It is to accept Jesus Christ's sacrifice for you, based on faith - this is a part of 'Love God', which is the first part of what you've said is required for Christianity.  Those who do not know about Jesus Christ are unfortunately to be sent to Hell - and so are those who have heard the Truth but reject it or are not sure of it.  This is, of course, Pauline Christianity (which is the only branch of Christianity that was allowed to remain to the present day, the other branches being destroyed as heresy).

The Muslim, therefore, who practices his religion and does not worship Jesus Christ as Lord and Savior is destined for Hell, through Christian doctrine.

Now I am not saying that Christianity is correct or incorrect, only that it is exclusive in nature, or rather, that the majority of practicing Christians would hold that it is exclusive.  There are less mainstream groups who would maintain that perhaps a correct belief in Jesus Christ is not necessary, or that the one who has not heard the Word of Truth may be saved, but certainly not the majority, whether scholars, pastors, priests, or laymen.

Having researched Buddhism myself, though certainly not to the extent to which I have applied myself to Christian thought, and thus not as an expert, I will say that the belief in a Big Bang is irrelevant for the Buddhist.

It's probably because religious discussion on here is led by atheists. And most atheists tend not to know much about non-Abrahamic religions.
If out of the Abrahamic religions, you're wondering why it's Christianity, I'd wager it's because it's politically incorrect to attack Jews and there's plenty of hate for Islam already.

haha no worries man I have no issues with you asking. 

So basically Buddhism has two major sects (pardon if I make mistakes here with the wording...trying to translate the word from my language to english is a bit difficult) ..one is Theravada and the other is Mahayana. To put it simply Theravada differs in the fact that they go by the scriptures and they are a bit less decorative in their approach to the religion. Theravada temples are very simple looking places compared to Mahayana etc...

The reason why I gave that is to let you know I am in fac a Theravada Buddhist. So my point of view is derived from that.

Life after death...yes we do believe in rebirth. As long as a person has desires they will be reborn. Their status or the situation in which they are born to is dictated by their actions. Good ends with good results and vice versa. As for where we will be born there are various categories of hells and heavens. All with their own specific nature that makes life better or worse. For example the worse the shit you have done in your life the worst hell you shall recieve and so on.

There are debates about this and my personal opinion (It's HEAVILY recommended that we form our own views and opinions on the teachings and not just follow them. Questioning it is encouraged, even at a sunday school level) is that both hell and heaven are places that exist within this same world. But that's just personal interpretation of it. 

As for Big Bang..honestly I'm not sure :D It's been ages since I have done any specific studying of the religion and I'm not the most religious person. So more likely than not I forgot. I am more than willing to look into it and let you know later if that's ok with you?

I do remember this though..there is one story in our books that speaks of a Monk who had this desire to find out where the universe ends. So what he did was using his mind he tried to explore the universe in order to find an end...in the end he failed and he got lost. Lord Buddha came to rescue him and he told the monk that it is an impossible task to do so he is better served trying to find answers to questions that are closer to him. ...at least that's the way I remember it hehe

Not sure about Christianity, but Islam dictates no compulsion in religion so that statement would be incorrect.

i also use the big bang theory. i've tied all religions together, and the different faiths don't have the same god. even people in the same faith have different gods. you can't believe in the same god, less you agree with everything, and everyone of your faith.

it's black or white, not rainbow colored.

edit: sin is in and of the church. church is the haven of demons and sinners, and if you believe in the devil. church is his home, so stop worshiping him.

WOW, you sound like someone that has actually read the bible, unlike most of people on this site. Anyways, I agree Christianity is exclusive, but unlike what some non-christians seem to believe, Chistians don't have a mandate to convert anyone. We can tell but not condem.

Awesome

If you do find out what your religion says about Big Bang or any other type of Science vs Buddhism/Religion then I'll love to see how they deal with it.

You mentioned Lord Buddha, is this like the Christian God, i.e. creator of all? Is there an equivalent figure to Jesus aka God in human form, in your religion? Sorry for all the questions, Google is broken

No compulsion, but active efforts at reasoning conversion because, under either system, the only way to achieve salvation.
