Hey, samuelboy2002!
Creative writing should be best drawn from your own interests and what inspires you. All my creative writings in Prelim and HSC English had musical elements in some way or another because that was what inspired me. I had a friend who wrote her creative writing on gaming because that was what she was interested in and was comfortable writing about. It really depends on what you will be motivated to write about and that's something you have to find yourself

Since you don't seem to have any ideas yet, I would suggest
looking at some past Band 6 responses in the AN Notes section. Although the previous module 'Discovery' is slightly different from 'Texts and Human Experiences', you can see what kind of topics people have written about in the past. You can check them out
here! You could also
draw inspiration from the rubric itself and your prescribed text for the module if you are really stuck. Identify parts of the rubric that resonate with your understanding of what it means to be human and let that guide your response. Your prescribed text has also been chosen for a reason, having various aspects of the human experience explored in them. You could select one to be a major theme or value in your own creative writing. For example, if you have
The Crucible or
1984, you could look at human instincts and sexuality as a key part of being human, forming a character that embodies that. On a different note, you could deem the social commentary and political agendas in
Go Back To Where You Came From or
Waste Land to be a way to ignite readers' understandings on human experiences and compose a creative writing with a similar genre, setting or message. This can be the best way to get something rolling and then you may find yourself figuring out that it's not right and you will know exactly what you want to do

It's okay to not know what you want to do with your creative writing because it is subject to change throughout the year as you engage more deeply into the course. As long as you have something you want to say, a grasp of how you should approach it and commence brainstorming ideas as soon as you do, you will power through it

If you have any further questions, do chuck them in this thread and I'll be happy to assist

Good luck with it and happy writing
