So many things don't add up in Genesis.
scripture is like many things in life, you have to study and learn to see what it means in a deeper level. That learning has to go in the right direction.
Like the Sun and stars, not only were they created after the Earth,
There were luminaries before our luminary (sun). They have drifted off into space. That is why it says Exist as light. That is not just the big bang it is stars (suns)
but created after plants?
that merely refers to our sun, and the stars now becoming visible
But then, I was wondering; Adam gets kicked out of Eden and has to till the soil? This is based on Gen 4:23 and 4:2 where Adam is sent out to "cultivate" the ground and his son Cain was a "tiller" of the ground. What did they till it with?
Genesis 1 tells us that there are other people. That is how Cain found a wife. This story relates a people on a land (if you are speaking of planet earth)
Did God make them a plow and a hoe or something?
see above
And then Abel, why was he keeping flocks? Weren't they vegetarians?
not by then
Was it for wool? Did God make Eve a loom and Abel some shears?

I see Genesis as religious poetry, but some Christians, and I guess some Jews, see it as literal. Ken Ham on his TV show Answers in Genesis, insists that it must be taken literal, that it is foundational, without it the whole of the Bible falls. What do you think.
It speaks >>>in a literal sense<<< of the higher-consciousness of God. That is the LITERAL bit. Because the nature of God works in a fractal way, it relates also down to us. But it will not be as ideal, as error always moves from realm to realm. We are the lowest realm other than death.
There were different periods of light, which allowed things to develop. Planets, vegetation, animals and then man. That is what it says. That is what science says.
A day, by the way, is a luminary (light). It does NOT say it is a 24 hour period. That is what we assume. Anyone going to the Pole will see that a day lasts for six months, and in outer space, a day may be a completely different amount of time. Time is relative.
There is always different angles of a story revealed that then make up the finished product. That is why it is hard to understand, which, as Peter says, some people twist to their own destruction.
