Hello Theatheist,
Welcome to TTI family.
First of all, I congratulate you for being an atheist. Why? Because you have already said and believed in the First Words of the First Part of Islamic Shahada. That is "Laa Ilaaha" (There is no God). The second Words are "Illallah" (But Allah), which we shall try to convince you to InshaAllah (God Willing).
Most of the people who belongs to different religions in this world are such because their parents are such. Christian because their parents are christian, Hindus because their parents are Hindus, Buddhist because their parents are Buddhist and even some Muslims are there who are Muslims because their parents are Muslims. These are the most ignorant of all.
We all MUST look for the truthfulness of our belief with our brain, with the modern science, with history etc etc.
The reason I congratulate you is because you ARE unlike them. You attempted to think about the God you worship. When you found that is totally falsehood, you chose to leave it, although your parents are having a different belief.
There are many people who were Christians before they changed their mind according to Atheism, who embraced Islam after further research on God's existence and on their Belief. Even TTI has some of them.
So this is your turn my brother in Humanity. Keep an open-mind unlike some people who came here before. Yeah their mind was not only closed, but sealed tightly, before coming here, and neither they, nor us were benefited from them.
As many brothers and sisters have already asked so many questions, I am not going to ask any, for now.
Have a wonderful stay with TTI family.
Peace
