Death isn't a better beginning... other than for the microbes and other critters that get to eat your remains as they are recycled by Nature. No beginning death be, it's the end of existence for the one that died... the beginning happened at birth...
Some people hope there is something more after death but the harsh facts of biology, life and death in the objective reality of Nature preclude that. Make the best of the life one has now, Carpe Vitae! Seize Life! Make a positive difference now that doesn't harm anyone! Make your existence mean something more than nothingness while you're here...
Ultimately that's all you can do, choose moment by moment to be the best you can be. When the moments run out we're just tear drops in the rain and gone forever.
After you're dead, you've ceased to exist. Your brain ceases to exist thus you can't know anything after you're dead. Only when you're alive can you realize that there is no after life for us... other than others remembering us. When it is their time they are washed away as well... like tear drops in the rain. Eventually all life will be extinguished and there won't be any memories of us in existence. Even if we managed to create AI life forms they'll eventually fade away too as the Universe experiences trillions of years of cold death. Eventually the universe won't be able to support sentient lifeforms anymore. Then no one will be around to observe the universe and it will be in a cold essentially static state of existence and nothingness.
It's hard to tell it like it is as most people don't want to hear the harsh facts of life in the objective reality of Nature were we actually exist.
Most people have a fantasy that they'll have some sort of afterlife, they hope or they have faith stricken beliefs about it... as if a story one tells oneself (or others) will have any impact upon the harsh facts of death and alter it in any way.
It's very understandable of course, who wouldn't want to exist forever?
It's also very greedy and selfish in the extreme to expect more from the Universe than it can give... but that to is understandable as who wouldn't want to exist forever in some magical disembodied form?
Hold on, disembodied like in a ghost? On some amorphous ambiguous plane of existence worshiping other beings as their slaves? No thanks, let the microbes and worms have me.
I'd rather Nature recycle my no longer functioning remains, at least that way I complete the cycle of life without some silly mythological fantasy wasting my brief existence.
