Do we need religions?

Now a days we are seeing lots of issues which are based on religion.
If you see materially, religions are not facts.
It is just a way of life which are practiced when there were no law and justice system existed. If you are doing good and doing right, do we require any religions? Religions will not give food for you. You have to work for it. Religious ideologies are myths. I think love is to be treated as a religion.
Be more human than religious to save this world.
Believe in reality and facts rather than myths to save this world.
In the current world, religious leaders believe their religion is superior than any other ones. This is a major cause of worry for the humanity.
