Your theory on afterlife is from a primate pathology to thijnk everything must begin and end.
Carbon based life forms are expiring, including our minds. Meaning we think everything is also time-based.
This happened through spiritual evolution, looking at the sun and wondering where we came from, why we are here, ect.
They started worshipping and praying to the sun, or Sol, the only thing that has been with us since the beginging of thought and judgement. This included plants and animals too, which also evolved from the sun and its influence on Earth and its geographical changes throughout history.
Now having said that, God was invented by humans by looking at time and assuming the universe "began", but ironically enough humans created time to cope with the thought that we "began" somewhere through a pathological progression embedded into our genes. Time suggests things must have a beginging in order to end, to predict where we are going and how long we have been around for... in other words, Genesis and Afterlife theories began. Religion was created through a stupid circle of events, creating a illogical hoolahoop of never-ending though patterns displayed in Christianity, Islam and other religons.
Scientists are no better, the big bang theory is yet another monkey thought based on time, not realizing that they are primates and cannot begin to fathom anything past their place, such as a dog is incapable of writing Mozart, no matter how hard it studies, tries or believes it can do it - it is simply restricted by its mind.
And that my friend, brings me to what God really is.
The universe does not end, it never began and created endless amounts of stars, planets and probably other life. It is bigger than we can possibly begin to comprehend, it is truly the one and only Alpha and Omega. It does not have to make sense on a time based scale with theories like the big bang or creationism as time only applies for Earth, it never needed to BEGIN anywhere to make actual "sense" to an insignificant primitive life form like homo sapiens. Hell, even "sense" comes from a primate mind based on time and Earth physics.
Basically, the universe the only thing we have ever come across that just IS and will always BE.
It is impossible for you or me to comprehend that the universe has always been around and never began, just like you can never teach a Dolphin to philosophise, but it is possible to understand that its logical, and have faith in it. Sound familiar? Here comes the circle again, because humans arent naturally able to understand anything outside of what nature needs us for. We don't need to know why and how, so any "logical" scientific or religious conslusion we as a species come to is false, unless you break the boundaries of time, genetics and history.
As for that higher force, look up the collective unconscience and exogenesis.
