Saying you can prove something like the religion of Christianity as false is as nonsensical as saying you can prove the language of English as false. Or proving Biology is false.
Do you mean proving God false? Because not all Christians believe in God (Christian Atheists), and there're a number of different ideas that Christians have about the nature of God - there are official Church doctrines, but then there are many who follow those Churches who believe in something completely different than the church they follow: for example, Catholicism is officially a trinitarian theology, but many Catholics still believe there is just one form of God, and don't quite understand trinitarianism; "God the Father" is a completely unknowable portion of God (basically, trinitarianism in a nutshell: God the Father exists outside of time and space, God the Son is his Word - the DNA/Code that makes up the nature/laws of the universe - and God the Holy Spirit is the physics or "breath/pneuma" that carries the word - The prophets are inhabited by the Word in order to preach doctrine; Jesus is the Word made flesh/Logos Incarnate). In short - there's no consensus as to what God is among Christians, trinitarianism isn't the core of Christianity, it is the doctrine Catholics accepted in the 4th century AD - you can somehow prove that wrong, but it won't make much difference.
You can potentially prove that Jesus never lived - but all that means is that churches will be forced to adapt their doctrines to focus on Jesus as a symbolic/allegorical figure, which isn't that big of a step for most churches today. Most churches don't really focus on biblical scripture as a historical documentary, but rather as inspirational or enlightening passages. Pure Christian literalism is actually fairly fringe, and I honestly don't think I have actually come across a Christian who is a pure literalist in my entire life... I have read about them "Westboro Baptist Church" (What is a "boro" anyway? Do they just spell Borough wrong?) but have never met any of them.
Basically, trying to prove Christianity as false is like trying to prove a fashion trend as false, or a language, or any other kind of cultural movement. You can prove elements about certain churches to be false, But even proving creationism false didn't end all religions that have a creation myth within them - and this isn't a recent occurrence either, even many religious people as far back as the Roman Empire didn't believe in creationism - St. Augustine, the most prominent non-biblical writer in Christian history, didn't believe in literalist interpretation of Genesis or creationism.
