Atheism is not the denial of God, it’s the refusal to believe in God without evidence.
So it’s the opposite of faith.
Believing something without evidence is faith.
Refusing to believe something without evidence is the opposite of faith.
Faith is just a term we use to justify believing in something which cannot be justified by available evidence. There is nothing glorifying about it and it’s not a reliable method to reach the truth.
The scientific method is not perfect but it’s the best method we have of reaching the truth. We have used it to build medicine, technology and put man on the moon.
Dear vitamin c, what do you mean by atheism is not denial of God? What do you mean by word evidence? Where is that evidence going to come from and how it is going to come? Who is going to decide the nature of this evidence and how? How will that evidence prove or disprove existence of God?
Word faith also means trust or confidence in or reliance or dependence or resting or basing or founding oneself upon someone or something but how can one trust in someone or something without needed evidence which helps one rely or depend or rest upon someone or something?
Unless people start learning how to look at these things systematically or methodically or properly they cannot be reasonably sure about anything at all and that is why they cannot assure or reassure themselves about things. For better understanding of deen of islam from the quran see HERE, HERE, HERE and HERE.
Evolution by chance or evolution by design is also a real issue for discussion. Before humans could figure out things they needed intelligence or faculty of discerning or ability or capability or capacity of making sense of things. Since intelligence requires a properly working circuit which could handle the software this is why hardware had to be there for it already. How did that precise hardware come about? When did it come about? Mind and body are two different things just like computer and its software. How did human brain come about and could a software work without brain or basic software that makes the hardware work at basic level? Learning things need capability within a system for self programming to begin with, so where did that software come from?
As we dig deeper and deeper into things, we see more and more evidence for a creator rather than no creator. We can clearly see coming about of things from things but by design and not by random chance otherwise we end up with infinite number of chances which lead us nowhere in the end other than in confusion and chaos or anarchy.
regards and all the best
