Well, Obama seems to have a decent, layman's grasp of the Big Bang, and other accepted science, and he's an attorney!
I know for a fact, because I watched Carson during the Republican debates, that he understands vaccines better than Obama. When given a question about vaccines and autism, Carson almost choked. He then equivocated. In a way, I have to give Carson credit for this. He didn't blithely accept the equivalence between autism and vaccines. So I suspect that is his medical degree kicking in. He did stammer that there was no connection, although he almost dies saying it.
However, I also note that Carson basically said that he would respect the freedom of people who think that vaccine. A politician listens to his followers, however dumb they are. Even when he thinks the opposite.
So the fact that Obama says that he believes in the Big Bang doesn't mean that he understands what the astronomers are saying. It basically says that more astronomers like Obama, for whatever reason. He would worship the Flying Spaghetti Monster if it had any real followers.
Obama does not know science better than Carson, or Trump. Obama flip flops on matters of science, like most politicians. As someone else said in another post, ‘When you become a politician, it becomes a matter of FOLLOWERS.’
The constituency of a politician dictates his opinions. Some people think it is the other way around. However, I think there are subcultures of people interacting in such a way as to act like a unit. They basically choose a representative.
I also know many attorneys who have this simple opinion about scientists. They call scientists 'whores'. They claim scientists are in the pocket of whatever special interest pays them.
Here are some of the things Obama has said about vaccines. He did change his mind, but what is important is why he changed his mind. He did not ever try to compare risks. He did not look at scientific projections. He looks at what reporters say in the public media. He looks what the biggest alarmist says, right ir wrong. He looks at headlines only.
He responded immediately to the crisis on hand. There was a spike in the rate of autistic births, some reporters said it was the vaccines, so it must be the vaccines. Then there was a spike in the rate measles infections, the newspapers said it was the lack of vaccines, so it must be the lack of vaccines.
Obama never said, let us look at the comparative risks of measles versus autism. He didn't extrapolate, interpolate, or weigh choices. He came to absolute evaluations based on what the reporters were saying that week.
Obama is not different from most politicians, left and right. They respond to headlines, not investigations and not studies. If a politician recommends an investigation, then it is on a topic that he already made a decision on. He tries to bend the investigation toward what the current headlines are saying.
Obama is as guilty on this as Trump. They have opposite opinions because their followers have opposite opinions. They do not pay attention to scientific study.
Here is some stuff on what Obama said about vaccines.

The exchange occurred on April 21, 2008, in Blue Bell, Pa. Here’s a transcript of the relevant portion:
"We’ve seen just a skyrocketing autism rate. Nobody knows exactly why. There are some people who are suspicious that it’s connected to vaccines and triggers, but -- this person included. The science right now is inconclusive, but we have to research it. Part of the reason I think it's very important to research it is those vaccines are also preventing huge numbers of deaths among children and preventing debilitating illnesses like polio. And so we can't afford to junk our vaccine system. We've got to figure out why is it that this is happening so that we are starting to see a more normal, what was a normal, rate of autism. Because if we keep on seeing increases at the rate we're seeing we're never going to have enough money to provide all the special needs, special education funding that's going to be necessary.”
If you want to hear how he said it, then look at this video.

Like most (al?) politicians, he reacts to immediate rather than long range problems. This means that he is sometimes right as shown by this link.

“I just want people to know the facts and science and the information,” the president said. “And the fact is that a major success of our civilization is our ability to prevent disease that in the*past have devastated folks. And measles is preventable.”
An epidemic of vaccination skepticism*— largely based on unfounded and discredited*anti-vaccine beliefs*— has contributed to the growing public health crisis.
Thanks to the widespread use of highly effective measles vaccination, the disease was effectively eliminated in the United States*in 2000.”
