Some experience from my life:
1) When my mother was ill, she had 39-40 degree C and couldn't move her neck and hand, I prayed for her and she got healed instantly, her temperature dropped to 36,6 after 5 min.
2) I prayed for one girl and she got healed from cancer
3) I told a prophecy to my freind, I said that he will pass exam, but God will surprise him, and he will get the highest mark not deservedly. He answered 1 of 5 questions and thought that will have 2 - the lowest mark but got 5 - the highest
4) When I was on exam, I asked God what question will teacher ask me and answer, and when I told the teacher what is giss thoughts, he afraid a little, Thanks to God I have graduated from university with all highest marks
5) I know people who healed from AIDS
And so on
I was seeking the God Half of my life and I still don't know him as I want to know. I learned to hear Him. Do you? Stop, please discuss about things that you don't know. And don't think that heaven is after dying. It starts when you fall in love with God.
God is almighty indeed, he saved your mom, your friend, a girl who had cancer, and some people who had aids.
But I guess all the kids that die from famine, lack of water and diseases every fucking second, dont deserve the love of your God.
It`s your right to believe, and I don`t want to judge you for that, but coming here saying that your God is true because he saved a couple of people, while he let thousands die, makes you look like an idiot.
Also you are wrong, Atheism is the suspension of belief due to lack of evidence. For the most part, we don't say that there is no god. We simply say that since there is no proof, there is no reason to believe in him.
When people of a certain religion call others atheists, I just want to laugh, throught history men invented thousands of gods, so basically a christian is an atheist to a muslim, a muslim is an atheist to a paganist etc etc..
Your god is unproven as any other god out there, thats why atheists dont want to believe in him, because most people don`t like believing in a "lie".
Also the bible is based on Egyptian, Chinese and Greek myths, that were born thousands of years before christianity
Virgin birth, burial in a rock tomb, eating the body *bread* and drinking the blood *wine*, these three are a small example that christianity is a fraud, if you do a small research, you`ll see that all these are pagan rituals, but christianity came as a snowball and rolled over thousands of gods & rituals, and named it Christian rituals
TL:DR version, The signs you see are illusions you create, because you want to believe god is true.
