Nicolau, you fail to understand that amidst all that crap we have to face, we get to have sex. Sex is even envied by angels.
Genesis 6:1,2 6 When human beings began to increase in number on the earth and daughters were born to them, 2 the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose.
Also, remember that fall made us sickly, we aren't inherently that way. Yes, death only exists because an angel turned snake made a dumb-butt eat a fruit. No, forget animals naturally dying. Forget evolution. The Bible provides all the answers. If you cease to question it, and simply accept it, you will grow to love the provision given to us.
The angels envy us and our incredible bodies because they cannot materialize. Woe to you angels, and your passing through matter!
