prove that god does not exist? can be done!

we know the time between nebucadnezer and cyrus. nebucadnezer was king 586 bc see chart below and king for 24 more years until nearer to jesus time, 562 bc.
586 bc destroy temple and exile see source below, and return of jews by cyrus in 538 bc [in first year] 48 years. "god should know 48" and religions claim "prophecy proves god", yet when we test a prophecy with a time, WE TEST A PROPHECY containing  A TIME, we see no god. this proves no god because god would tell a prophet 48.  the prophecy claimed more until return, 70 years is false.
cyrus was dead by 529 bc, see chart, long before 70 years. god would know the future, not seventy years yet god 70 in chronicles 36.20-21 and the book claims fulfilled, there and ezra 1.1-4 [page 398 of niv] so also we know the book of jew and christian is false.
we can know "no god" by testing prophecy because god would know less than 70 years and tell a prophet the correct number, so by finding a prophecy with a time, jeremia 52.27 and cronicles 36.20-21 and since cyrus sent them back before 530 and jew tradition announces 537 bc only fifty 50 years this proves judea christian faith and book is a lie and also "no god who knows" that the return was less than 70.
586 before christ exile 2 cron. 36.20-21 with nebucadnezer known to be that year
+50
538 before christ return with cyrus
+9
529 bc cyrus dead
516 time frame of "god" seventy years, long after jew returned by cyrus
CONCLUSION we test a prophecy with a time because "no time is worth zero trash" and we see god does not exist based on prophecy of jewish and christian faith.
if i said "a woman or obama-colored man or woman will be president" of USA and then Mrs. Clinton lost in 2008, i can say "I did not say a time" wait until "the end of times" that is worth zero garbage so revelation 1.1-4 says soon and near. which begs the question, what idiot in year 300  decides to include revelation in a book that said "soon"- ?? jesus christ ! 300 years after jesus know "not soon" and that soon is false.
other prophecies lack time frame, so "garbage like me predicting a woman president."
jona said 40 days and not true, so rabbis defend "a prophecy for punishment" differs from a good prophecy a bad can be cancelled and not areal  "test". in contrast return is good and can be tested even sin will not cancel a good prophecy and here it was less exile proving no god and jewish and christian religions based on lies.
