There's no hell, no afterlife , no reincarnation, none of that.
Read a book on neuroscience , evolution , or molecular cell biology to see what a human really is.
After death is non-existence forever
boggles my mind that people believe so many things without any evidence . you can read a book on the biolgogy of cell , evolution , or brain science and test things yourself and you see the details all fit together and sub details and parts to many levels. i always need to see how things work or I don't believe them . i don't believe in anything without evidence or that i can't see how it works the details. It's easy to say an abstract general idea . when when you get to the details or how it works , or how to get something done is when you see it break down and what it really means or how impossible it is. for many things a general abstract idea is meaningless. that includes afterlife, soul , simulation, multiverses, reincarnation etc.
All organisms all life descended from a single cell. the following is just a few paragraphs of evidence of which there is 1000's of books of evidence , experiments , microscope images , etc. The ancestor of humans is a single cell.
Evidence of common descent of living
organisms has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating that
all life on Earth comes from a single ancestor. This forms an important part of the
evidence on which evolutionary theory rests, demonstrates that
evolution does occur,

There has been little doubt as to whether life on Earth arose from a single ancestor. This has been supposed from areas such as the universality of DNA and the commonality of central intermediary metabolism in cells.
Theobald has extended this inference to a formal test of whether UCA is a better explanation than independent sources of life. His results show a clear outcome of the hypothesis from which the question can be
answered:
Did life evolve from a universal common
ancestor? Yes, yes it did.
A remarkable uniformity exists in the nature, assembly, and utilization of the basic molecular components of all living organisms. The degree of similarity in the genetic information stored within the DNA, biomolecules, metabolic pathways, and other cellular and biochemical processes point toward the genetic continuity and common ancestry of living organisms
Molecular biology
Like structural homologies, similarities between biological molecules can reflect
shared evolutionary ancestry. At the most basic level, all living organisms share:
• The same genetic material (DNA)
• The same, or highly similar, genetic codes
• The same basic process of gene expression (transcription and translation)
• The same molecular building blocks, such as
amino acids
These shared features suggest that all living things are descended from a
common ancestor, and that this ancestor had DNA as its genetic material, used
the genetic code, and expressed its genes by transcription and translation.
Present-day organisms all share these features because they were "inherited" from
the ancestor (and because any big changes in this basic machinery would have
broken the basic functionality of cells).
Although they're great for establishing the common origins of life, features like
having DNA or carrying out transcription and translation are not so useful for
figuring out how related particular organisms are. If we want to determine which
organisms in a group are most closely related, we need to use different types of
molecular features, such as the nucleotide sequences of genes.
Homologous genes
Biologists often compare the sequences of related genes found in different
species (often called homologous or orthologous genes) to figure out how those
species are evolutionarily related to oneanother.
The basic idea behind this approach is that two species have the "same" gene
because they inherited it from a common ancestor. For instance,humans, cows,
chickens, and chimpanzees all havea gene that encodes the hormone insulin,
because this gene was already present in their last commonancestor.
In general, the more DNA differences in homologous genes (or amino acid
differences in theproteins they encode) between two species, the more distantly
the species are related. For instance,human and chimpanzee insulin proteins are
much more similar (about 98% identical) than human and chicken insulin proteins
(about 64% identical), reflecting that humans and chimpanzees are more closely
related than humans and chicken
The origins and evolution of the ribosome, 3–4 billion years ago, remain imprinted in the biochemistry of extant life and in the structure of the ribosome
As the molecular mechanisms of life have become clearer, the underlying similarities among organisms are more impressive than their external differences. For example, all living organisms store genetic information in nucleic acids (usually DNA) using a common genetic code, transfer genetic information from DNA to RNA to protein, employ proteins (and some RNAs) to catalyze chemical reactions, synthesize proteins on ribosomes,derive energy by breaking down simple sugars and lipids, use adenosine triphosphate (ATP) as their energy currency, and separate their cytoplasm from the external environment by means of phospholipid membranescontaining pumps, carriers, and channels.Retention of these common molecular mechanisms in all parts of the phylogenetic tree is remarkable, given that the major groups of organisms have been separated for vast amounts of time and subjected to different selective pressures. These ancient biochemical mechanisms could have diverged radically from each other in the branches of the phylogenetic tree, but they worked well enough to be retained during natural selection of all surviving species.The cell is the only place on earth where the entire range of life-sustaining biochemical reactions can function, so an unbroken lineage stretches from the earliest cells to each living organism.
