How do you prove something doesn't exist? It's a ridiculous notion, hence Bertrand Russell's Cosmic Teapot analogy.
As for forcing opinion on others, that's a specialty of Christians, who are urged by by their instruction book to spread the word of their God, to be missionaries and disciples ('And he said to them, “Go into all the world and proclaim the gospel to the whole creation. Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.' or 'Go therefore and make disciples of all nations' for example), but not to question, not to ask questions, not to look for proof or evidence, just have "faith".
By the way, the evidence of 21st Century Christians - a book edited in the 17th Century, based on a 16th Century translation of 8,000 contradictory copies of 4th century scrolls that claim to be copies of lost letters written in the first century. All of which promotes misogyny, homophobia, infanticide, incest, rape, genocide and informs us the Earth is the center of the universe and is 6,000 year old. At least science attempts to understand and explain by research, by test and re-testing, by working with provable evidence, by opening up to peer review for others to research and test and re-test. It may not (yet) prove God doesn't exist, but it has brought us out of the dark ages, reduced our ignorance, expanded our knowledge of the universe and disproven much of what the bible claims about the make up of everything.
