I highly recommend watching this video by Jeff Cavaliere: https://www.youtube.com/watch?v=hCDzSR6bW10 https://www.youtube.com/watch?v=hCDzSR6bW10 as a checklist of things to think about before attempting a deadlift. The key thing that he calls out in this and other videos is that most people do not have sufficient hamstring flexibility to safely deadlift off the ground (lack of flexibility will force your back out of a neutral position "rounding of the lower back"). There is certainly no shame in starting your deadlift from an elevated position by stacking plates underneath the barbell or pulling off rack pins while you work long-term on improving flexibility. I highly recommend watching any of his videos before attempting any exercise, even ones that you think you know how to do well, e.g., bench press :)
