As a convert to Islam, I was brought up a Catholic until I was about perhaps 8 or so. I know it's not that much but I was socialized apparently into Catholicism. Then my parents kind of stopped believing in religion for a little while, so I was not socialized religiously for a while. When we were living in Florida we went to Protestant church, for a little bit... Then we stopped, then 9/11 and I as a child looked into "what happens to me if I die?" Because I had experienced a lot of spiritual things in my life for me not to believe in something that cannot be explained by "science". For example, science still contests whether we are pushed into earth or pulled by gravity. There are so many things that cannot be explained by science. So I sought out going to church and I pushed my parents to go church and listen.
Of course, I didn't feel convinced because some things didn't make sense to me... Like the trinity, lol. It has never made sense to me. To think that God has a son and God needs a spirit to communicate with you...? How can God have a son? In Catholicism I couldn't understand why if Jesus sacrificed himself for the sins of people would children need to be baptized in order to remove this "sin" when children are born innocent and without the sins of their fathers....I also could not understand the images, the random images in the churches and the asking to Jesus for forgiveness, why not God directly? Why would we need to ask someone who was born on earth for forgiveness? I was not convinced at all. I was also thrown off by the pastor message to the congregation that they needed to be "poor" whilst giving alms.. And then going to the pastors home where he was not poor, but he owned a large land of about 100 acres and this was his vacation home. Excuse me? Are we paying for you to live this kind of life, while we bask in misery?
There were so many things. Perhaps experiences of life, having the chance to travel and see the world that I learned more and more. Alhamdellah, thank God I have been blessed with the opportunity to travel the world and have experienced first hand the spiritual world. For example, when I was younger I used to have constant visits at night by something. This thing bothered me and tormented me until I was older. I haven't seen it in a while, Thank God. My brother has also experienced a lot of spiritual things, although he's kind of agnostic and very technological since he does engineering. He acknowledges the spiritual side and holds belief that there is a God.
As for me, I traveled overseas and when I heard the Adhan in a Muslim country, I felt something deep in my heart. This is coming from someone who disliked Islam before working overseas. So people can change, it requires travel and experience in my opinion. You have not traveled, until your travels have impacted you in one way or another. I have found a lot of people who have gone to Muslim countries have changed their way of life or opinion about Islam. For example, my little brother and mom used to think horrible about Muslims, until I took them to a Muslim country and they loved the experience, the people, the sound of the Adhan. Although their hearts might be a little tougher than mine, since mine has always been yearning for that full feeling, their change will take a little longer than me. I also had the chance to live there, while they just visited for some time.
So take it as a convert

as someone who has explored many religions and traveled around. Perhaps it is my positive experience living in a Muslim country that has changed my view most of all. I felt safe, like I could walk around at night and be safe or leave my doors open. Right now I am waiting to travel to the uk ان شاء الله for my PhD and I am traumatized and scared of living in the uk by myself. My mother is also scared, so she comes with me lol.
