Countless christians have claimed this about their lifetimes for thousands of years now, including most importantly the first christians who were directly told that the end days would happen in their lifetimes.
Unless you are aware of some dates in the bible naming the early 2000s as the end of days? (note: god specifically says in the bible that nobody will know the time).
much much nastier back then, yes. in contrast to back then, when human civilization was always at war with each other everywhere, where diseases wiped out massive swaths of the population on a regular basis, where most of humanity survived in near starvation, where rape and murder and violence were a daily part of life, nowadays the vast majority of humanity live their entire lives far from any wars, famine has been wiped out, we are far healthier and longer lived than ever, and the concept of human rights and rape laws are the rule of thumb over most of the globe.
You believe God came from nothing. You're accusing yourself of being irrational.
And there's nothing in nature that requires a divine explanation, and most every thing that humans thought needed a divine explanation has turned out to have a simple scientific one.
