Religion's are different path ways to God if followed properly , comprehending our existence to sooth your mind and soul.
Are they for everyone ? no , and neither is heaven. Which can be interpreted as a mind state rather than a physical place.
Most people just don't want the accountability for their actions and thoughts, and the responsibility for their role on this planet. Influence is the greatest power. Shame and ego can keep people from this also. It can be scary for most once the truth is seen.
You can be intellectually lazy and a coward, aka athiest. But that's your choice and is ok, just realize when you "do what you want" that means others can "do what they want" to you, so don't complain.
If you don't know the answers , you haven't asked the right questions. Finding nirvana is reserved for those who have done and continue to do the work.
God Bless
