Science isn't an entity and therefore incapable of believing anything at all.
If you meant "Do scientists believe in the existence of God?" then:
Some scientists do believe in God[ess](s) and others don't. Though there seems to be a correlation between the two in consideration that the majority of some major scientist associations particularly in Europe (i.e. Britain and Sweden), to a lesser extent the USA (and elsewhere in the world as well) tend to be non-believers or express significant doubts.
No, if it did it wouldn't be science.
Science does not provide direct evidence for the existence of God as it focuses on natural phenomena and observable data. The existence of God is a matter of faith and belief, which is beyond the scope of scientific inquiry.
I assume they believe in the existence of God.
Monotheists believe in the existence of only one God. They believe that this one God is the creator of the universe and the ultimate authority. Monotheistic religions include Christianity, Islam, and Judaism.
Science doesn’t have the processes to prove or disprove the existence of God. Science studies and attempts to explain only the natural world while God, in most religions, is supernatural.
Many Christians believe they have a duty to talk about their belief in the existence of God. Even when people believe, not in the existence of God but in the existence of other gods, some Christians insist on voicing their opinion that he exists. Of course, on a level playing field, those who do not believe in the existence of God have an equal duty to express their beliefs.
Agnostics are people who are unsure about the existence of God. They neither believe nor disbelieve in the existence of a higher power.
Science does not make any definitive conclusion about God.
Science recognises things that are provable. Since the existence of a god or gods is a matter of faith it is not amenable to scientific evaluation it fall outside the realm of the scientific method. That is not to say that some scientists do not believe in a god, many do.
Unitarians believe in the existence of God, but they emphasize the oneness of God rather than the traditional Christian doctrine of the Trinity. They believe in the unity of God and reject the idea of God as three distinct persons.
There is no proof for or against a "god" or his or her existence. What you believe and not believe all comes down to faith.
Most people in Science would say there is no god, as some parts of Science teach against the existence of a God or Deity, instead processes of natural selection and evolution.
