Apologetics
Apologetics is an area of study that basically proves the existence of God. There are a lot of people who have set out to disprove "Christianity" - but, instead became very outspoken proponents arguing that there is a God.
When I was born again in 2014, I wanted to be sure I was right, and there really was a God and that there was proof. So - if you have the same desire, there are some very interesting presentations, websites, and readings to help you get your most difficult questions answered.
Good Listening...
If you are just getting started, I recommend listening to some of Frank Turek's presentations. He is very entertaining, and very knowledgeable.
You can also read his book - which has much more than he has time to go into during his presentations. Book: I Don't Have Enough Faith To Be An Athiest
Recommended Books:
Paul Copan: Is God a Moral Monster
J Warner Wallace: Cold Case Christianity
Lee Strobel: The Case for Christ
​
Many of these authors have multiple books.
Online Resources:
There are a lot of YouTube presentations you can listen to that can educate you on multiple sides of the "is there really a single God" argument. I found this compilation of videos that will provide hours of interesting and informative listening:
