Atheism is no new thing
Ask the vast majority of atheists today why they believe what they believe (i.e. that there is no God) and why they don't believe the Bible, and they'll most likely give you an answer along the lines of "well the Bible was written thousands of years ago by ignorant and superstitious people, and we know live in the twenty first century, and have vastly superior scientific knowledge to the ignorant nomads of Bible times; therefore we no longer have a need to believe in the myths that these people believed".
They claim they are modern, scientific thinkers. "We're too intelligent and intellectually sophisticated to believe all this nonsense", they say.
But real history tells us that this is just not so. King David who wrote the Psalm below around 1020 years B.C., which is about 3000 years ago now, records for us exactly the same atheism as we see in the world today.
Psalm 10
1Why do You stand afar off, O LORD? Why do You hide Yourself in times of trouble?
2In pride the wicked hotly pursue the afflicted; Let them be caught in the plots which they have devised.
3For the wicked boasts of his heart's desire, And the greedy man curses and spurns the LORD.
4The wicked, in the haughtiness of his countenance, does not seek Him All his thoughts are, "There is no God."
5His ways prosper at all times; Your judgments are on high, out of his sight; As for all his adversaries, he snorts at them.
6He says to himself, "I will not be moved; Throughout all generations I will not be in adversity."
7His mouth is full of curses and deceit and oppression; Under his tongue is mischief and wickedness.
8He sits in the lurking places of the villages; In the hiding places he kills the innocent; His eyes stealthily watch for the unfortunate.
9He lurks in a hiding place as a lion in his lair; He lurks to catch the afflicted; He catches the afflicted when he draws him into his net.
10He crouches, he bows down, And the unfortunate fall by his mighty ones.
11He says to himself, "God has forgotten; He has hidden His face; He will never see it."
12Arise, O LORD; O God, lift up Your hand Do not forget the afflicted.
13Why has the wicked spurned God? He has said to himself, "You will not require it."
14You have seen it, for You have beheld mischief and vexation to take it into Your hand The unfortunate commits himself to You; You have been the helper of the orphan.
15Break the arm of the wicked and the evildoer, Seek out his wickedness until You find none.
16The LORD is King forever and ever; Nations have perished from His land.
17O LORD, You have heard the desire of the humble; You will strengthen their heart, You will incline Your ear
18To vindicate the orphan and the oppressed, So that man who is of the earth will no longer cause terror.
There's modern day atheism described in detail in a supposedly antiquated irrelevant book.
It seems to me that it's atheism that's antiquated and irrelevant.
