You can't prove or disprove God with Science (also you need to pick specific fields of Science). God is an Omnipotent, Omniscience, Omnipresent being that exists both outside of Time and in Time. Effectively you see God every day in everything.
This is where you get into the New Testament descriptions, the Apostles, the life of Jesus (who has been historically proven), miracles, historical events, etc.
Now you could hint at parts of Science pointing to God. People cite to certain intelligent designs in creatures, the unexplainability of the pre-Cambrian explosion, the uniqueness of the rock formations at the Grand Canyon, the flaw in Science of saying Earth was formed by accident, rotation of planets, flaws in some of the fossil finds, etc. I find all that speculative and some of these arguments are questionable. I think these "hints" are not solid arguments under Scientific theories but a lot of stuff isn't. As people pointed out here, modern "science" is often not true science (at least as shown in the news). I have relatives in science and it is always a search for answers. Take Oppenheimer, the scientists in it rarely come to consensus, often turn on each other for political reasons, take educated guesses and assumptions, etc. This is real science, the search for answers. Let me tell you a surprise, there are Scientists teaching all throughout our nation and world today that believe in God. If Science disproved him, than explain these Scientists? On a personal level, I don't believe Science will ever PROVE or DISPROVE God nor do I think Science has truly explored our Universe. It is hard to make the claim when we haven't even left our Solar System in a Universe with Billions of Galaxies each with Billions of Stars.
Also different arguments work for different people. The Bible records that people even saw angels, miracles, etc. (like the Jews in Exodus) and still denied God. In many instances, you can never convince some people even if they had direct proof.
I will say this, it is hard for me to imagine millions of people willing to undergo the punishments/persecution that they faced for something they believed to be a lie. The life of Paul (a life of total change and sacrifice) is a great example. Also, as even shown by Richard Dawkins recently, the move away from Christian values in the West have NOT made things better and has caused some real issues. Now, we don't need to turn into a religious state nor am I advocating passing any laws favoring Christianity (or even favoring the ten commandments going into school as discussed in this thread), I am just pointing it out on a personal stand point.
