I also believe all religions and atheists / agnostics are valid perspectives and should not be discounted. As others have stated, humans are limited in our understanding, and we should not put finite standards on comprehends divinity / scientific study of the world. Essentially, yes, all will get a chance of heaven in my view. I agree that it is "our deeds and not creeds" that allows God to embrace us.
