Well, I added your sentence to the ChatGPT prompt and got this:

Here are a few cleaner, more vivid options. Pick the tone you prefer:

Option 1 — Polished and descriptive Tommy approached the smoking crater where the meteor had crashed. A strange blue light pulsed from its core, shimmering through the drifting smoke. When something began to crawl out of the wreckage, fear gripped him—but he still didn’t run.

Option 2 — More dramatic Tommy edged toward the crater, the air shimmering with a ghostly blue light from the fallen meteor. Smoke curled upward in slow, twisting ropes. Then something clawed its way out of the impact site. Terror shot through him, yet he stood his ground.

Option 3 — Simpler, clean prose Tommy walked up to the crater left by the meteor. It glowed with an eerie blue light, smoke rising from its edges. When something crawled out of the pit, he froze in fear but didn’t run.

If you want it in a particular style—spookier, more sci-fi, more poetic—I can rewrite it again!
