cant provide you the answer of how universe came into existence.. but just because the scientific community doesn't have the answer as we dont have the supporting evidence.. that doesn't mean I start believing religous data based of fantasy....
Just because we dont know the value of a=? that doesn't mean a=flying horses...
Now I wont ask you about creation or theology... I will ask you a simple question, do you believe in quran and hadiths, do you beleive in miracles performed by prophet muhammad?
You are comparing apples with oranges. You need to understand that God is not a material being. Material evidence of God would be rather silly. scientific method does not operate on supernatural entities. We have detailed discussion and argument in this topic. Take some efforts to read few pages of this topic to understand the differences between belief, fact, truth

BELIEF - Something which is held to be true by an individual.
FACT - A statement that can be proven.
TRUTH - A statement that is correct
Most things which people tend to discuss as beliefs are not facts which means they cannot be or have not been proven, though they still may be true. for example if someone say Dolphins are more intelligent than human beings now this statement could not verified or disproved so its for peoples what they believe.
For example wine is good or wine is bad? Now can you tell which statement is based upon fact? You cannot so peoples will have different beliefs about whether wine is good or bad. If someone say wine contains ethanol and will cause an intoxicated state of mind if consumed then this is a scientific statement of fact. Notice how we can do an experiment based on the scientific theory that wine causes intoxication. By simply drinking a quantity of wine we can evaluate the truth or falsehood of this statement.
Take another example of Creationism vs the Big Bag Theory. The first is a belief and without proof or disproof, it may or may not be true. The Big Bang theory is widely accepted by scientists as the best explanation we have but it is still theory, based on assumptions and no true scientist will tell you otherwise. The scientist may choose to believe that the theory is correct but that is still a belief, no more or less valid than the person who believes in God's creative genius. Some people will also claim that God created the universe using the Big Bang. Again, this is merely a belief, unprovable either way.
The question of the existence of god is not a scientific question. God is not observed in nature except by inference of his presence by a particular observer. A Christian might observe god in the sunset, while an atheist might only observe diffraction and diffusion and chromatic extinction of sunlight. Many scientists may believe in a god and many highly unscientific people may not believe in god. There are many different kinds of people on planet earth.
