Contradiction with Ecclesiastes 1:2

Ecclesiastes 1:2: Vanity of vanities, saith the Preacher, vanity of vanities; all [is] vanity.
Contradiction with Ecclesiastes 8:17
This verse suggests that humans cannot fully comprehend the works of God, which might appear as a contradiction to the idea that God's works are great and sought out by those who delight in them.
Ecclesiastes 8:17: Then I beheld all the work of God, that a man cannot find out the work that is done under the sun: because though a man labour to seek [it] out, yet he shall not find [it]; yea further; though a wise [man] think to know [it], yet shall he not be able to find [it].
Contradiction with Job 5:9
Implies that God's works are beyond understanding and cannot be fathomed, which could suggest a challenge in seeking them out as presented in Psalms 111:2.
Job 5:9: Which doeth great things and unsearchable; marvellous things without number: [unsearchable: Heb. there is no search] [without...: Heb. till there be no number]
Contradiction with Isaiah 40:28
States that no one can understand the ways of God, which contrasts with the idea of his works being great and openly understandable to those who seek them in Psalms 111:2.
Isaiah 40:28: Hast thou not known? hast thou not heard, [that] the everlasting God, the LORD, the Creator of the ends of the earth, fainteth not, neither is weary? [there is] no searching of his understanding.
