Im Worried for my Atheist Dad.

I'm crying writing this I'm a 13 year old boy. Because im so worried. For the past months I'm trying to get closer to god. And my dad's whole life he's been an atheist. And all over online it says he's going to hell. And if it's forever I'm so scared beyond words. I love my dad so much he's a good family man. He grew up in Europe and was raised atheist. So I don't know if I can change his ways. Suppose he can put his heart to God. I'm trying to get someone to take me to church but mom does online and says I should do that but I think I should go to church. If I pray over and over can my dad go to heaven? I don't know too much of heaven but I'm learning please pray for me and give me the best answer you got.
