William Dembski Quote

Scientists rightly resist invoking the supernatural in scientific explanations for fear of committing a god-of-the-gaps fallacy (the fallacy of using God as a stop-gap for ignorance). Yet without some restriction on the use of chance, scientists are in danger of committing a logically equivalent fallacy-one we may call the “chance-of-the-gaps fallacy.” Chance, like God, can become a stop-gap for ignorance. – William Dembski

Yes, you do have the right to believe anything you want.

We have a right to believe whatever we want, but not everything we believe is right. ― Ravi Zacharias

People tend to have a hard time accepting that they could be wrong about something. I admit I am wrong all the time and I often have to swallow hard before I do it.  Quite frequently I bump up against people who run out of answers for my questions and accuse me of trying to take their right to believe what they want away from them.   I am not trying to take away anyone’s rights. You have a right to believe that green is red, and red is green if you want to, but I would not suggest you try to drive a car.  It doesn’t matter how strongly you believe the light in the middle of the road is green, if it is really red. Eventually your wrong belief is going to hurt. But if on the other hand you believe that green is in fact green and red is in fact red your life will be enriched by the truth you will more safely be able to drive a car and many other things will come into proper focus with your true belief.
When I witness to people I am not trying to take away anyone’s rights, I am telling people what I think is true, and it has served me well.
And I am hoping that you will see my truth as true, and that your life will be enriched by that truth as well.

You can believe what ever you want. If you want to believe that everything in the universe is comes from nothing and the order in the universe sprang from random chance you are free to do that.  If you want to believe we are all a dream of some deity and nothing is real you can believe that too. But be prepared to realize that one of us is wrong.
