First of all Jesus didn't create man but God with the aid of Jesus,
IF YOU DONT BELIEVE in the Bible many theories have been offered over the years: evolution, ancient alien theory, panspermia etc. In that line of thought we have no purpose and no meaning as previous mentioned.
IF YOU BELIEVE in the Bible then the answer is quoted in Genesis 1:26-27: “Then God said, ‘Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky...’ So God created mankind in His own image, in the image of God He created them; male and female He created them.”
God is a Creator and created a being in his image to look after this planet because He can, like He created angels before that.
Now if you want to dig deeper, there are many rabbit holes you can follow and the following is just pure speculation based in Scripture. I believe one of the reasons we were created is for some of us, only the ones that get raptured, to replace Satan and 1/3 of the angels that fell from Grace.
While the Bible doesn’t explicitly state that humanity was created to replace fallen angels, several verses suggest that believers in Christ will occupy significant roles in God’s eternal kingdom. These roles may parallel or even surpass those held by angels before the fall:
Judges of Angels:1 Corinthians 6:3: “Do you not know that we will judge angels?”
This verse implies that redeemed humanity will have authority over angels in God’s eternal kingdom. It suggests a reversal of the hierarchy seen in creation, where angels initially held a superior role to humans.
Heavenly Worshipers:Revelation 7:9-10 describes a great multitude of redeemed humans worshiping God before His throne, a role previously associated with angels (e.g., Isaiah 6:3).
Adopted as Sons and Daughters:Hebrews 1:14 explains that angels are “ministering spirits sent to serve those who will inherit salvation,” indicating that humanity, as heirs of salvation, has a unique and exalted status in God’s plan.
