Is there any evidence of Kraken?

Excuse me, but could you elaborate on the existence of Kraken? Have there been any credible sightings or reports that suggest its authenticity? Are there any scientific studies or historical documents that provide evidence of its existence? Furthermore, have there been any attempts to capture or study this creature, and if so, what were the results? I'm genuinely curious to know if there's any solid proof that Kraken is more than just a myth.
