I dont often get peeved BUT it so happens that I lodged with a masters level quantum physiscist who was a Christian and I happen to know several active scientists who do believe in 'creationism' so it isnt something I have just made up! These are highly intelligent people and ususally I drop out after the first 5 mins of conversation because I understand very little of science but they all conlude that there is no conlusive proof for the big band in fact they suggest that it is Highly unlikely and point out many inconsisencies in the theories.
Because of your past record I do not know if you are making this up or not. But let's say that you aren't.
At first I have the problem that I can't argue with anyone because you don't know anything and this person is not here.
I can tell you that at no university in the world it is taught that the big bang theory is highly unlikely. I have spoken with several astronomy professors and they all claim that the main idea of the big bang is rock solid and that they are at this point adjusting the small details. If you look at the history of the big bang theory, the christian friendly one and named 'big bang' by atheists to ridicule it, and its opponents, you will see why this is.
So you may claim the big bang theory is wrong. But that is just not the opinion of science. I am not saying the big bang theory is right becuase all of science says so. I say it is right because based on observations of reality it is the best theory.
Yes, there is no conlusive proof. Science does not give conlusive proof, ever. No scientist can give me conlusive proof that if I release an apple it will drop to the ground and not fly up into the air.
You claim that you stop listening after 5 minutes. Then maybe you miss out this brainwashed, but intelligent, religious guy getting whiped around the room in argument. The fact that this person is religious and a student doesn't mean anything.
...they concur that it is much more rational to hold to a biblical view of Creation, which whilst not giving all the detail, gives a much more solid starting point for development - in their view.
Their view is wrong. And if you can give me their arguments I can say why. If you can't then your comment is useless. I don't know if this is a discussion tactic or not.
So before you go calling folks ignorant you should check your sources a bit better.
Which sources do I need to check? Do you assume that because this guy says things you don't understand and don't even try to listen to for more than 5 minutes it must be right? There are no scientific sources that say the things you claim these people say.
And yes, they are ignorant. Or they are just saying something else then you claim they are saying. Observe how you fused stupid and ignorant. You claimed that they are intelligent and therefore they can't be ignorant. This guy isn't taking astronomy. And if he did take astronomy he failed to learn anything. Otherwise he wouldn't have said the things you claim he said.
As for creationism providing a more solid basis for science. That's just absurd. If creationism were true the world would be totally different. If Genesis 1 and 2 had really happened the world today would look different. Genesis 1 and 2 contradict reality.
It is in theory possible to propose an alternative theory of creation. Maybe the persons you describe have one. But I don't know about it. I don't know any alternative creation theory alternative from the bible. As long as I don't have this theory I can't say anything about it. It would be interesting to see how this theory would handle all the evidence that seem to make the big bang theory rock solid. Not to mention darwinistic evolution. Darwinistic evolution is true. Why would a creator create a world and then add evolution? How do they work together. Etc.
If you dont want Christians to put forward biblical views on topics the bible speaks clearly about then you need to organise the heading of your threads better. Like 'a secular discussion of the big bang theory - no fundaentalist Christians allowed' - is one possible title. I was under the misapprehension that this was an open forum??! 
Maybe you should assume that every person that wants to discuss or talk about a subject would like to do that in an intelligent way and with somewhat informed people. That's what I do. Bibical views are barbaric and uninformed and to assume they are allowed in a discussion about a subject within the field of science is silly. It was already been proven to be a bronze age myth.
